How do you show someone the force of an erupting volcano via print, or the height of the Burj Khalifa over a 17-inch screen?

No matter how huge something may be, it's hard to wrap your mind around the scale of it without seeing it for yourself, or having some point of reference to compare it to.

That's where this trope comes in. A simple way to show the size of something is to compare it to something else that a lot of people are familiar with. That's why many documentaries, especially ones of the "World's Biggest Whatever" variety, will use measurements that compare things to familiar or historic events, places, and objects.

* Energy: Released by explosions and hurricanes: will be measured in atomic bombs dropped on Hiroshima. When trying to be slightly more specific, they use "kilotons of TNT". Electricity will be measured in "enough to light up X% of [[BigApplesauce Manhattan]] for Y amount of time".
* Height will be measured in Empire State Buildings, Eiffel Towers, or Pyramids of Giza. Really big heights will be compared with Mt. Everest or any of the other famous mountains (Denali, K2, Anapurna, Matterhorn, etc).
* Volume and concentration will be measured in Olympic swimming pools.
** In the UnitedKingdom, volume is sometimes measured in Albert Halls (and as [[Music/SgtPeppersLonelyHeartsClubBand The Beatles]] told us, 1 Albert Hall = 4000 Holes).
** In UsefulNotes/{{Australia}} liquid volumes are sometimes measured in Sydharbs (the amount of water it would take to fill Sydney Harbour, or about 500 gigalitres).
* Lengths will be measured in trips to the sun, times around the Earth's equator, or distance between the Earth and the Moon. The mean distance between the Earth and the Sun is used as an actual unit of measurement, the Astronomical Unit (AU). Smaller lengths (comparatively speaking) might be measured as the distance between two points, e.g. "Enough copper wiring to stretch from Chicago to Minneapolis".
* Small lengths will be compared to the thickness of a human hair. Also acceptable is the head of a pin, as in how many of what can fit on one. Also acceptable: amount that can fit in the eye of a needle. Another uncommon one is how many of something can fit inside a period ([[NoPeriodsPeriod the punctuation mark, you pervert]].)
* Area will be measured in football fields, or compared to that of some region (Wales, Texas, Switzerland...).
* Weight will be measured in sacks of concrete, Boeing 747 jumbo jets, VW Beetles (for some reason, it's always VW Beetles or Mini Coopers), or large animals (usually elephants and whales, or sometimes [[BreadEggsBreadedEggs both]] [the tongue of a blue whale could fit 3 elephants on it]).
* Large amounts of money are generally measured one of three ways:
## as the length of that many one-dollar bills laid end-to-end, using one of the astronomically-sized length measures, e.g. "If the National Debt were in dollar bills and you laid them end-to-end, it would stretch all the way to the sun and back 9 times."
## in stacks of dollar bills (for truly large amounts, larger denomination bills may be used) using one of the standard comparative-height measurements ("One million dollars would be a stack of dollar bills one and one half times as tall as the Empire State Building").
## by how much a person would have to spend per day/hour/minute/second without stopping for ("To spend a billlion dollars, a person would need to spend $1901.32 ''every minute'' without stopping for a year")
* Small spherical objects (mostly hail) will be compared either to fruit or sporting equipment (grapefruit, golf-balls, etc).
* Anything to do with zoology and especially paleontology will use the average human height.
* A population will be measured by how many football/Olympic stadiums they could fill.
* Absurdly high temperatures will be compared to the Sun, the melting point of certain metal, or a (possibly self-cleaning) oven.
* Despite stronger metals existing for a long time (like tungsten carbide and carbon steel), compressive and tensile strength is still compared to steel (e.g. spider's silk/nylon/carbon fiber is X times stronger than steel). Sometimes compressive strength is compared to concrete.
* Animal strength will invariably be compared either to how much a bulldozer can lift; or, for small creatures, to how much they could carry/lift/jump if they were blown up to human size ([[SquareCubeLaw ignoring the problems being human sized would cause them]]).
* Fat and calories will often be given in units of cheeseburgers or large pizzas.
* Because any amount of radiation sounds scary, the BED was invented ([[http://en.wikipedia.org/wiki/Banana_equivalent_dose Banana Equivalent Dose]]) to help people understand small amounts are inconsequential. {{xkcd}} touched upon it [[http://xkcd.com/radiation/ here]].
* The size of vehicles are often given in terms of other vehicles.
** For ships the standard is usually ''The Titanic'' or "an aircraft carrier".
** For smaller automotive sized objects, a VW Beetle will be the yardstick. For larger objects, (especially in North America) a Greyhound bus may be the comparison.

Basically, any unit of measure that equates to something extreme in that property, [[AMillionIsAStatistic but is still rather vague and hard to comprehend since the average person doesn't know what that ''is'' off the top of his or her head]]. Bonus points if the number of the unit of measure is still ridiculously large (e.g. 1,000,000 Hiroshimas) thereby defeating the purpose of describing it in those terms even if the unit was something people would intuitively understand.

Many of the units on Wiki/{{Wikipedia}}'s [[http://en.wikipedia.org/wiki/List_of_unusual_units_of_measurement list of unusual units of measurement]] are of this form.

This trope is for unusual units for quantities that have well-defined values in ordinary non-facetious units. If you measure an amount of something that usually is not given a numerical value at all, such as "evil" or "beauty", it is an AbstractScale. See also FantasticMeasurementSystem.

[[folder:Anime]]
* ''Anime/SpaceBattleshipYamato2199'' describes the FloatingContinent found on Jupiter as around the same size as Australia.
* ''Manga/SilverSpoon'''s Hachiken attempts to measure large measurements like hectares in Sapporo Domes. A RunningGag is that no-one ever actually knows, but compares it to something else (for example VaticanCity or [[Anime/SuperDimensionFortressMacross the Macross]]) only for Hachiken to realise he has no idea how large the new unit actually is.
[[/folder]]

[[folder:Comic Books]]
* There is a story by CarlBarks with DonaldDuck and his nephews, where they are travelling into space via a virtual machine [[WesternAnimation/DuckTales Gyro Gearloose]] made. Donald takes them to bigger places where he recreates earthly stuff on vast scales, constantly using comparative scales for his nephews and the readers to grasp. This is mixed with using objects of continuously lesser scales -- first insects, than dust, snowflakes, etc -- surpassing them. The story is called 'Donald's Big Imagination'. A grasshopper from Betelgeuse is imagined having 5 ocean liners on its back and the circumference of the star uses a time-scale analogy, namely "Earth's fastest rocket takes 100 years to fly around it".
[[/folder]]

[[folder:Documentary]]
* The documentary ''Series/WalkingWithDinosaurs'' mentions the meteorite at the end of the Cretaceous as "hitting the Earth with a power of 100,000,000 Hiroshima bombs".
* Seven years earlier, ''Series/PlanetOfDinosaurs'' did this straight ''three'' times. The Meteor Crater was made by a rock which hit the Earth with an impact like 4 Hiroshima bombs; the Tunguska Event (1908, in Siberia) was provoked by a mysterious body with a power of 1,000 Hiroshima atomic bombs; finally, the iconic meteorite of the End Cretaceous with its [[UpToEleven 100,000,000]] Hiroshima bombs.

[[folder:Film -- Live Action]]
* The movie ''Film/{{Armageddon}}'' uses this trope while describing the size of the asteroid.
-->'''President:''' How big are we talking?
-->'''Scientist:''' Sir, our best estimate is 97.6 billion--
-->'''Dan Truman:''' It's the size of Texas, Mr. President.
* ''DeepImpact'' features a comet described as "The size of New York City, from the Battery to the Bronx. Or, put another way, it is larger than Mt. Everest." The opening narration also used the "Hiroshima measurement" when speaking of the asteroid that wiped out the dinosaurs. Even though they try to make it sound impressive, they ''severely'' [[YouFailPhysicsForever underestimate]] the energy released by the real impact.
* In ''{{Jarhead}}'', this is noted as a legitimate military tactic to quickly gauge distances: use things you know, such as the length of a football field.
-->'''[=SSgt=]. Sykes:''' You take what you know, and then you multiply. Please don't use your dicks. They're too small, and I can't count that high. I don't wanna hear, "400,000 inches."
* In the film ''TheGiantClaw'', the SpecialEffectsFailure creature is constantly compared in size to a battleship.
* ''Film/{{Sunshine}}'''s ''[[WhatDidYouExpectWhenYouNamedIt Icarus]] Two'' is built around "a stellar bomb with a mass equivalent to Manhattan Island". (How heavy is Manhattan Island? That depends on how thick it is.)
* In ''TheAbyss'', Lindsey asks Lt. Coffey how many missiles are on the wrecked sub they are investigating:
-->'''Coffey:''' Twenty-four Trident missiles, eight [=MIRVs=] per missile.
-->'''Lindsey:''' ''({{beat}})'' That's a hundred and ninety-two warheads, Coffey. How powerful are they?
-->'''Coffey:''' The MIRV is a tactical nuke. Uh, fifty kilotons, nominal yield, say... five times Hiroshima.
-->'''Lindsey:''' Jesus Christ. It's WorldWarIII in a can.
* In ''Film/Cradle2TheGrave'', the second-most powerful setting of the superweapon is described as "two Hiroshimas". The number-one most powerful setting is described as "new world order".
* The Soviet movie ''Operation Y and Other Adventures of Shurik'' has this personified in the construction foreman -- he gives a lengthy speech consisting entirely of this trope, culminating [[http://www.youtube.com/watch?v=Ouz4l_lAK7A&feature=player_detailpage#t=420s in one of the movie's many]] CrowningMomentOfFunny.
--->'''Foreman:''' ...twice as tall as the world-renowned Eiffel Tower, or thrice as tall as the famous Notre Dame de Paris, incidentally, that's French for "Our Lady of Paris".
--->'''Brute:''' (nonchalantly) Whose lady was that?
--->'''Foreman:''' (taken aback) Our. Of Paris.
* In ''{{Help}}'', as Music/TheBeatles record a song in the middle of Salisbury Plain with the Army protecting them, the bad guys burrow underneath, setting a massive amount of explosives labelled in military-grade stencil "Equal to exactly one millionth of the explosives exploded in one week of the Second World War".
* In ''Film/IndependenceDay'', when describing the mass of the alien mothership, it's said to be "a quarter the size of the moon."
* ''Film/{{Ghostbusters}}'': Egon uses a convenient Twinkie to describe the current PKE levels in the containment unit. Ironically, he gets something about the size of Mr. Stay-Puft.
[[/folder]]

[[folder:Literature]]
* A children's book called the ''I Wonder Why Encyclopedia'' occasionally measures weight in terms of small cars despite also giving actual units and somehow deciding that cars weigh exactly one ton.
** The problem with this is that it's a moving target. A "mid-size" 1981 Dodge Aries and a "small" 2008 Toyota Yaris both weigh about 2500 lbs.
* In Creator/FredSaberhagen's "Literature/{{Berserker}}" series, the Berserker enemy A.I. spaceships are often described as the size of Manhattan Island. Which for a space ship is HUGE.
* ''New Scientist'''s Feedback column maintains a discourse on unusual units used in media and advertising lasting probably since its inception -- London buses, blue whales, football pitches etc etc etc.
* The children's book ''HowMuchIsAMillion'' teaches kids about large numbers in this manner.
* The problem with trying this sort of thing is lampshaded in one of the ''Literature/TheHitchhikersGuideToTheGalaxy'' books, explaining that the titular guide (known for its breezy style) gets around the whole problem simply by stating "Space is big. I mean really big. You may thing it's a long way down the road to the chemist's, but that's just peanuts compared to space."
* ''Literature/{{Discworld}}'': According to an advertisment in the ''The Compleat Ankh-Morpork City Guide'', every bowl of Makewar's Crispy Nuts breakfast cereal contains the same amount of nuts as three squirrels.
* In the ''Literature/SkylarkSeries'', instead of giving the hardness of arenak and inoson on the Mohs scale, or the strength of arenak and inoson in pounds per square inch at failure, they are said to be "500 (or 2000) times harder and stronger than the hardest and strongest steel".
* GeorgeCarlin's ''When Will Jesus Bring The Pork Chops?'' has a dialogue in two parts, entitled 'Tumor Humor', wherein a group of women and a group of men talk about the sizes of tumors taken out of an acquaintance's body. The difference illustrated is that the women compare to produce ("a tumor the size of a grapefruit") while the men use sports equipment ("a tumor the size of a basketball") as their baseline.

[[folder:Live-Action TV]]
* ''HowDoTheyDoIt'' described a ship as "the length of three football fields" and "six times the size of the ''Titanic''" within one minute.
* ''Killer Asteroids'' on the Science Channel describes asteroids' power in terms of Hiroshima bombs.
* The narration writers for The History Channel series ''ModernMarvels'' love these, even when they're less than helpful. Particular favorites are "the thickness of a human hair" or some fraction of it; aircraft carriers for size or volume; and football fields, or "Los Angeles to {insert appropriate city}" for distance. Of course, before you can describe something's size in units of aircraft carriers, you first have to mention that an aircraft carrier is the length of 5 football fields.
* The ''Series/DoctorWho'' ChildrenInNeed special "Time Crash" said, as a joke, that the explosion caused by the time crash will make a hole in the space-time continuum exactly the size of Belgium. The Fifth Doctor remarks that Belgium (as a unit of measurement) is a bit underdramatic, but a bit later uses it as a shorthand for the catastrophe, as in "Two minutes to Belgium!"
* The "How to be Well" public service announcements on Creator/{{Nickelodeon}} stated that one pecan pie has the same amount of fat as twelve cheeseburgers.
* Many documentaries on ships will give the size of the ship as measured in ''Titanic''s.
* Parodied in ''Series/MontyPythonsFlyingCircus'', as part of a spoof documentary on Tchaikovsky.
-->'''Graham Chapman''': Well, if you can imagine the size of Nelson's Column, which is roughly three times the size of a London bus, then Tchaikovsky was much smaller. His head was about the same size as that of an extremely large dog, that is to say, two very small dogs, or four very large hamsters, or one medium-size rabbit if you count the whole of the body and not just the head.
* ''Series/CosmosApersonalVoyage'':
** In a chillingly poetic comparison in the last episode, Creator/CarlSagan compared the total tonnage of bombs dropped in WorldWarII -- about 2 megatons of TNT -- to the yield of a single modern strategic thermonuclear weapon. Given the size of the world's arsenals at the time, the tonnage of bombs and warheads we could theoretically drop in WorldWarIII, he said, would be "A world war 2 every second, for the length of a lazy afternoon." He then went on to say that this was the equivalent of a million Hiroshima bombs.
** In an earlier episode, he quoted another scientist saying that all the energy ever collected by all the radio telescopes in the world is less than the energy of a single snowflake striking the ground.
* The ''Series/{{Angel}}'' episode "Time Bomb" had the demoness Illyria threatening to implode and, according to Wesley's conservative guess, take out several city blocks. Angel requests an "unconservative" guess.
-->"Rand & [=McNally=] will have to redraw their maps."
* These kind of measurements come up on ''{{QI}}'' from time to time. Apparently the UK purchases enough wrapping paper for the Christmas season every year to gift-wrap the island of Guernsey.
* AnimalPlanet likes to compare animals' caloric intake with numbers of hamburgers. Like, a vulture eats the equivalent of 50 hamburgers in one sitting. (Scaled down to the body mass of a vulture, of course. If a vulture ate 50 actual hamburgers, it would explode.)
* In the "Earth from Space" episode of ''Series/{{Nova}}'' (Creator/{{PBS}}), they showed the brine released from freezing water in the antarctic cascading downward under water. It was said to be 500 times the flow rate of Niagara Falls. Earlier in the same episode, they described the energy absorbed by all the water vapor evaporating from all the Earth's oceans in multiples of the entire energy production of all power plants in the world combined.
* On ''Series/HowItsMade'', when discussing the manufacture of steel coffins: "This requires 900 tons of pulling force -- the equivalent of hoisting 27 fully loaded tractor-trailers."
* In the '60s Walter Cronkite once pointed out that the Apollo space capsule had as much room for a three-man crew in bulky spacesuits as the front seat of a Volkswagen (then [[IReadThatAs universally understood]] to mean a classic Beetle) meant for two in normal street clothes.

[[folder:Newspaper Comics]]
* ''TheFarSide'' had a panel inspired by writings about how fast a school of piranha can skeletonize a cow. He thought this was an odd thing to use as the standard unit of measurement, and since his comic regularly features cows anyway, this inevitably became the basis for a panel: Two cows in pith helmets and hiking gear are exploring the Amazon, and one of them reads the statistic from a guidebook, commenting "...now ''there's'' a vivid thought." Note that the cows are standing in a piranha-infested river while reading this.

[[folder:Tabletop Games]]
* ''Advanced'' ''DungeonsAndDragons'', 1st Edition, used the gold piece as a unit of weight. Your carrying capacity, the lifting power of a ''telekinesis'' spell, the load limit of ''Tenser's floating disc'', etc. -- all these were given in units of gold pieces rather than pounds. (At the time, 1 gold piece weighed 1/10 of a pound, so converting between pounds and gold pieces was rather easy, although it did make for some ridiculously heavy coins. When 2nd Edition came out, the weight of 1 gold piece changed to 1/50 of a pound and the notion of listing weight in g.p. was abandoned.)

[[folder:Video Games]]
* ''KatamariDamacy'' uses this form of measurement to illustrate the size of your katamaris.
* ''Franchise/MassEffect'' tends to use Hiroshimas to quantify the yields on starship [[MagneticWeapons mass accelerators]], both in-game and in the Codex. One [[MemeticMutation particularly memorable scene]] from ''2'' has a gunnery captain chewing out a pair of recruits about just how powerful the gun really ''is'', and how important it is to check their targets.
-->"This, recruits, is a twenty-kilo ferrous slug. Feel the weight! Every five seconds, the main gun of an ''Everest''-class dreadnaught accelerates one to one-point-three percent of light speed. It impacts with the force of a 38 kiloton bomb -- that is ''three times'' the yield of the citybuster dropped on Hiroshima back on Earth! That means '''Sir Isaac Newton is the deadliest sonofabitch in space!'''"
** Also, in ''VideoGame/MassEffect1'', Admiral Hackett will use it to describe the size of a tactical nuke attached to a ''recon probe'' launched during the First Contact War.
* Grobnar of ''VideoGame/NeverwinterNights2'' starts using his team mates as a unit of measurement.
--->'''Grobnar:''' No one really knows how big the Wendersnaven are. They could be thousands of Khelgars high!

** And then parodies the practice [[http://xkcd.com/1257/ here]].
* In ''Webcomic/{{Goats}}'', Phillip needs one of these to comprehend the number of people he's killing every time he creates and destroys another universe:
-->'''Yakmeat''': Every time we run a simulation, we are literally creating an entire artificial universe to experiment with. And when an experiment is over, we're just turning off quadrillions of lives.
-->'''Phillip''': I can't conceive of a quantity that large. It's meaningless. You're speaking jibberish.
-->'''Cornhusk''': Each termination can be reduced to a function of 3.5 billion times the number of people exterminated by Adolph Hitler in your level's second world war.
-->'''Phillip''': Oh my God. 3.5 gigahitlers? Each time?
* Dave in ''Webcomic/{{Homestuck}}'' mediates on this trope over instant messaging:

* ''TheNonAdventuresOfWonderella:'' Author Justin Pierce explains in TheRant that an upcoming multi-part comic will be handled by adding extra panels to the bottom of a single page, rather than spreading it out over multiple pages. Then [[http://nonadventures.com/2012/12/22/very-spatial-wonderella/ he starts measuring the length of the comic in "Toms"]]:

* Technology discussion boards have used "Libraries of Congress," in reference to the physical U.S. legislative library of the same name, as a measure of storage capacity. Various actual figures are occasionally tossed around as a baseline (often hovering in the tens of terabytes), but they vary widely, and now that people with a cursory knowledge of computers are familiar with kilo, mega, giga and terabytes, the term is now used as a joke more often than not.
** A similar comparison was used in ''Literature/SnowCrash'' to describe the speed of the novel's fiber-optic data transfers:
--->'''Narrator''': In order to transmit the same amount of information on paper, they would have to arrange for a 747 cargo freighter packed with telephone books and encyclopedias to power-dive into their unit every couple of minutes, forever.

* When the fanbase compared the size of ''SuperSmashBros Melee'''s "Final Destination" stage to that of ''Brawl'', someone had the idea to use a ''character'', cloned and stood end-to-end, as a unit of measurement.

** Areas are measured in units of ''Wales'', ''Belgium''s and ''Democratic Republic of Congo''s, and ''Football Pitches'' (soccer fields). One ''Wales'' is a thousand ''[=MilliWales=]'', one million ''[=MicroWales=]'' and one billion ''[=NanoWales=]'' respectively.
** Force is measured in units of ''[[ChuckNorris Norris]]''
** Lengths are measured in units of ''Linguine'', ''Double-decker bus''es and ''Brontosaurus''es. One foot is approximately 2.1772 ''linguines'', 0.0331 ''double-decker bus''es and 0.0022 ''brontosauri''.
** Temperature is measured in units of ''degrees [[Creator/ParisHilton Hilton]]''. Zero degrees Hilton is 68 degrees Fahrenheit (20 degrees Celsius), the temperature of a comfortable room. One degree Hilton is defined as the amount of heat required to make an average person remove a layer of clothing (+10 degrees Celsius).
** Volume is measured in units of ''Walnut''s, ''Chicken eggs'', ''Grapefruits'', ''[[UnusualEuphemism Bulgarian Airbags, Bulgarian Funbags]]'', ''Footballs'' (soccer balls, not pigskin) and Olympic-sized swimming pools.
** Weight is measured in units of [=Jubs=] -- A [=Jub=] is 1000000 [=MicroJubs=], 1000 [=MilliJubs=], and 0.001 [=KiloJubs=] respectively.

* The ''WesternAnimation/LeapFrog'' educational DVD ''Scout and Friends: Adventures in Shapeville Park'' featured mice called "measure mice" used as part of a song number about measuring. "Look at Penny jump / How far can she go? / We can use the measure mice and then we'll know / Line them up and count them up, place them end-to-end! / Her jump is two mice long! That's how long!" The mice were cute and the song was catchy, but the problem was that no real-world units were given to relate just what "two mice" was. Some felt this may have been done to avoid having to get into confusion between metric and imperial units, but more than one reviewer and commenter on Amazon.com felt the idea of measuring with mice was somewhat bizarre.
** As opposed to common-sense units of length, such as the foot size of a long-dead king, or one ten-thousandth of the distance between the north pole and the equator.

** They are almost always measured in kilo/megatons. That means that they are as powerful as that many thousand or million tons of TNT. Little Boy, the bomb dropped on Hiroshima, was somewhere between 13 and 18 kilotons.
*** It would take about 4 kilotons of TNT to fill an Olympic swimming pool.
** Wikipedia also uses the [[http://en.wikipedia.org/wiki/Tsar_Bomba Tsar Bomba]], the biggest nuke ever made, to measure the eruptive power of [[http://en.wikipedia.org/wiki/Krakatoa the Krakatoa eruption]]. (Hint: 1 Tsar Bomba = 3,125 Hiroshima bombs, and 4 Tsar Bombas = the Krakatoa eruption)
** The energy released by a large meteor impact (like the one that killed the dinosaurs) is often likened to collecting all the nuclear weapons in the world to one spot and exploding them all at once, then repeating it about 1,000 times within the same second (for a more precise comparison, the energy released by the impact of a meteor with a 10km diameter is about 100,000,000 megatons. The Hiroshima bomb was 0.016 and Tsar Bomba 50 megatons).
** Project Rho has a handy [[http://www.projectrho.com/public_html/rocket/spacegunconvent.php#id--Nukes_In_Space--Boom_Table Boom Table]] listing energy release in joules, equivalent mass of TNT and example phenomena that might cause such an event.
** It is worth noting that comparing earthquakes and volcanic eruptions in general to nuclear explosions is quite imprecise, and has been known to irritate some geologists. Earthquakes tend to distribute energy across a wide area, but nukes are an adequate approximation for explosive volcanic eruptions (like Mt. St. Helens, or Thera) and meteor strikes (like Tunguska); one need only compare the depth of a crater or radius of a blast to see.
* In America, many people will emphasize how small or remote a town is by listing the miles to nearest Wal-Mart, [=McDonald's=], major grocery store, or multiplex.
** Hint: You're never farther than 115 miles from a [[http://www.datapointed.net/2010/09/distance-to-nearest-mcdonalds-sept-2010/ [=McDonald=]'s]]
*** This doesn't include Alaska. If it did, it'd be a ''lot'' further than that.
*** under 40km in Germany! [[http://www.mcdonalds.de/metanavigation/mcfinder/mcfinder.cfm source]]. Unless you count Helgoland, where the nearest restaurant seems to be in Cuxhaven, some 60 km away.
** City size can also be described similarly; [[Series/BuffyTheVampireSlayer Sunnydale]], for instance, is "a one Starbucks town."[[note]]Despite the fact that the town contains a university, airport, and ''castle''.[[/note]]
* In America, Rhode Island's status as the ultimate in mass land-area equation technology is legendary, it having been founded for just such a purpose by the British to convey meaningful analogies of claimed territories to the Throne. If the area being described is too big to be measured reasonably in Rhode Islands, it's often measured in Connecticuts, South Dakotas, fractions of a Texas or fractions of an Alaska.
** ''Our Dumb World'', an atlas by the Onion, describes Rhode Island as being "[[ShapedLikeItself roughly the size of one Rhode Island]]", which is to say: about 1/3 the size of Puerto Rico, or 76 times smaller than Portugal.
** Creator/GeorgeCarlin quipped that you could build "two Rhode Islands and a Delaware" on the land that's currently being used on golf courses in America.
** ''The CIA World Factbook'' describes the land area of ''every'' country in the world this way: "about half the size of Texas," "about the size of South Dakota" and in one or two cases "approximately three times as big as The Mall in Washington DC."
* PJ O'Rourke once [[LampshadeHanging lampshaded]] this trope, on a tour of a US Navy vessel, and came up with a few comparisons of his own, deciding for instance that the ship contained [[ComedicSociopath "enough rope to hang every Democrat elected to Congress since the Johnson administration."]]
* For height, the preferred unit in the US is the Empire State Building. The Eiffel Tower is also used fairly often. For geologic height, it's Mt Everests.
** For UsefulNotes/{{Sydney}}, Australia, it is the Sydney Tower.
** BritishNewspapers prefer to include a range of comparisons to whatever the subject is, including a double-decker bus, Big Ben (St Stephen's Tower), St. Paul's Cathedral, Canary Wharf, The Eiffel Tower, the Empire State Building, the Petronas Towers and any other really famous skyscraper.
*** [[http://www.theregister.co.uk/2007/08/24/vulture_central_standards/ Mercilessly parodied]] by online BritishNewspaper ''The Register''. Be warned that some of the examples listed may be NotSafeForWork
** Mt. Everest occasionally appear as a unit of mass or weight. One science special declared that if all the mass in a single wooden matchstick were converted to energy, it would be enough to lift Mount Everest 20 feet off the ground.
* Welsh comedian Rhod Gilbert has commented on BBC newsreaders' practice of describing areas of land as being the size of Wales:
--->I know what you're thinking when you say it: "An area the size of Wales, ''[angrily]'' but ''not'' Wales!"
* Eohippus, the tiny ancestor of horses, is almost universally described as "about the size of a fox terrier". What makes this case particularly interesting is that this comparison is considerably more well-known than the size of a fox terrier itself, at least among paleontologists. Stephen Jay Gould [[http://books.google.com/books?id=etKX2s6JgAkC&pg=PA163&lpg=PA163&dq=eohippus+fox+terrier&source=bl&ots=RayCMOp0IC&sig=CdVL2RMgq52vJn0c8bPnbkWgKS8&hl=en&ei=iAxITbSjH4LEgAel1YSoBg&sa=X&oi=book_result&ct=result&resnum=3&ved=0CCoQ6AEwAg#v=onepage&q=eohippus%20fox%20terrier&f=false wrote a lengthy article on the origin of this meme]]. Today, the "fox terrier" comparison is outdated. So now textbooks just say Eohippus was "about the size of a modern dog". Granted, there's such a wide size range among modern dogs that this is rather less helpful.
* The snipers in many armies are trained to judge distances with their eye, by getting them to think about a specific distance that they personally know a great deal about. Due to the nature of people who work as snipers, this often results in the distance being measured by eye in terms of "how many football fields long".
* And, of course, every dinosaur's brain is about the size of a walnut.
** Similar to the above, it's common (mostly in documentaries) to compare the size of anything prehistoric with the size of a dinosaur. For instance, you typically won't get through a documentary talking about marine reptiles like Mosasaurus or Tylosaurus without having the narrator mention how it was "X times bigger than a T-Rex".
* One measurement for caloric content is to compare foods to the equivalent number (or fractional number, as the case may be) of [=McDonalds=] Big Macs (540 calories, 27% of the average recommended daily caloric intake). Discussed in one ''Webcomic/PvP'' strip, where Skull notes that even monsters do that (one plump Bavarian kid is apparently equivalent to 500 Big Macs).
** A somewhat more peculiar measure: ''The Economist'' invented, and uses, a measurement called "The Big Mac Index" to compare currencies; since [=McDonalds=] is very strictly standardized, the price of a Big Mac directly corresponds to what it costs for the restaurant to serve it; as such, comparing the cost of a Big Mac to currency exchange rates can tell you when a currency is under- or over-valued.
*** In some places (like Italy) the measurement is skewed by the very large, nearly 100%, "tax on junk food": a Big Mac in Florence may cost 6.5 euros (7.88 USD), while the same Big Mac in Vienna, where junk food is not taxed, only costs 3.5 euros (4.24 USD).
* Astronomers routinely measure the masses of stars and other heavy objects in increments of "solar masses". The masses of extrasolar planets are usually measured in increments of Jupiter masses or Earth masses.
* Inverted. When the atomic bomb was first dropped on Hiroshima, ''Time'' magazine described it as seven times the power of the [[http://en.wikipedia.org/wiki/Halifax_Explosion Halifax explosion]].
** A regular example at the Halifax memorial museum. The Halifax explosion is described as the biggest single explosion before the Trinity Test in July 1945 and the bombing of Hiroshima a month later.
* In the US, hail is infamously measured in "balls". That is, is the hail the size of a ping-pong ball/golf ball or a baseball? This is, of course, because hail is small and round. Balls are small and round, so the comparison is understandable.
** Smaller hailstones are often compared to US coins, such as quarter-sized or dime-sized. Even smaller hailstones may be considered "pea-sized"
* Number of deaths will be compared with the Black Plague or the Holocaust. For example, people often assume that the Black Plague of the 14th century was the worst pandemic ever. The Spanish Flu killed twice as many people in a shorter amount of time. It's also used to try and impress upon people the [[http://www.webmd.com/hiv-aids/news/20020125/aids-worse-than-black-death importance of AIDS research]]. Another example is trying to explain to Americans how deep of an impact WWI had upon its populace. What with wiping out a whole generation of young men and all.
** The Black Death vs. Spanish Lady comparison shows two different ways of looking at how deadly a disease outbreak is: The former is very bad in terms of proportion of the population killed, the later in terms of total number of deaths. The Black Death killed, over a span of approximately ten years, about one person in three in Europe, making it one of the most lethal disease outbreaks of all time. The Spanish Lady killed a much smaller fraction of a much larger population, taking many more total lives (more than were killed in WWI, in fact, but with less dramatic social impact because they were more scattered through the population instead of being heavily concentrated among young men).
* Late night hosts began measuring time in "Kardashian Marriages", a unit of approximately 72 days.
* In the world of writing things very small, which is exactly as fascinating as it sounds, the standard unit is 'bibles per square inch'.
* "The Potrzebie System of Weights and Measurements," described in ''Magazine/{{Mad}}'' #33, is largely similar to the metric system, but with different base units. The standard unit of length, the potrzebie, is defined as the thickness of ''Magazine/{{MAD}}'' #26 (2.263348517438173216473 mm). The Potrzebie System was sent in to ''Magazine/{{Mad}}'' by then-19-year-old Donald Knuth, who became a famous computer scientist. This is also a case of FantasticMeasurementSystem, though based on a real-world item.
* [[http://www.inference.phy.cam.ac.uk/sustainable/book/tex/usa.pdf This article on renewable energy]], on page 2, measures how much land each type of renewable energy would require in units of ''New Jerseys.''
* This article from TheOtherWiki lists [[http://en.wikipedia.org/wiki/List_of_humorous_units_of_measurement several of them]].
* Theoretical physicists frequently write their equations in terms of [[http://en.wikipedia.org/wiki/Planck_units Planck units]], units derived by setting each of 5 fundamental constants of the universe equal to 1. While these units have the distinction of being "natural," in that they're not bound to an arbitrary quantity like the size of the Earth or the mass/oscillation speed of a particular atom, their magnitudes make them completely impractical for everyday measurements. The Planck unit of length, for example, is about a hundred-quadrillionth the width of a proton, and the Planck unit of temperature is about 10^25 times the core temperature of the sun.
* In the game of Twenty Questions, players would usually ask if the object in question is bigger than a breadbox. [[WhatAreRecords Few people own breadboxes anymore]], but then again few people play Twenty Questions either.
* [[http://www.bbc.co.uk/news/uk-scotland-edinburgh-east-fife-23861397 This article]] describes a microscopic bead that spins "half a million times faster than a domestic washing machine and more than a thousand times faster than a dental drill."
* The temperature on Venus is typically described as "hot enough to melt lead".
* Many common units of measurements likely started this way. For example, an "atm" is the pressure of sea level Earth's atmosphere, a "bar" is an amount of pressure about that of Earth's atmosphere, but consistent with metric units. Temperature scales were based on boiling and freezing points of water -- Celsius sets 0 and 100 at those points for distilled water, while Fahrenheit originally had 32 as the freezing point of water and 96 as human body temperature.[[note]]Fahrenheit gave 32 as the freezing point of water, 96 as the average body temperature of a human being, and 212 as the boiling point of water. However, scientists who came after him could not set a scale that got all three of those values to correctly line up with the things they were measuring, so they took the two they could measure precisely -- the freezing and boiling points of water -- and adjusted the third accordingly, giving us the modern standard of 98.6 for human body temperature.[[/note]]
* Needles prevent hedgehogs from combing out parasitic insects that fall on them. Thus parasitologists came with a "hedgehog-hour" -- the number of ticks a hedgehog collects after 1 hour walk in a tick-infested area.
* Pretty much all scientific units of measure are based on some property of some physical object, most commonly water.
* Gaming website Rock, Paper, Shotgun has a running tradition of comparing a game's size to its equivalency in "Peggles", the total size of a copy of Peggle (21-ish megs).
* The [[http://en.wikipedia.org/wiki/Smoot smoot]] is a unit of length defined as the height of MIT Alumnus Oliver Smoot (5'7"). The MIT chapter of Lambda Chi Alpha adopted this unit of measurement when they wanted to figure out the length of the Harvard Bridge.
* Storage devices for computers are often measured in quantities of files commonly stored now. Such as a 16GB thumbdisk holding 30,000 images or 5000 hours of music or 300 hours of video. All of some standard quality of course. Sometimes they're compared to other storage formats, like 4 DVDs or 23 CDs or 11,000 floppies.
