** Comparison of [[http://www.schlockmercenary.com/d/20050208.html two]] [[http://www.schlockmercenary.com/d/20050305.html strips]] from the ''sixth'' book suggest he's confused diameter and radius.

* ''EarthTheBook'' ends with a survey for the reader to fill out as an "Application for Genetic Reconstitution by Aliens." One of the questions is "How many kilowatts would you say your brain produces hourly?"

* Often times Creator/JulesVerne's books contained measurements and spot on calculations. However, when they were brought over to the UK and US the translator screwed up horribly on the conversions at first. Partly by not really even doing them. Just replacing the metric unit with the rough alternative, but keeping the numbers. H.W. Starr's famous [[EpilepticTrees theory]] that Nemo was [[Literature/SherlockHolmes Professor Moriarty]] uses as part of its evidence that he wasn't the noble figure he presented himself as the "fact" that the crew quarters must have been horribly cramped compared to his stateroom, based on the figures in the original English translationyrjöperskeles.

** An example involving a unit made up for the show. Early on, it was decided that time on the station would be measured in cycles, possibly to avert TwoOfYourEarthMinutes. Unfortunately, none of the writers seemed to be able to agree on what a cycle was equivalent to (i.e. is it an hour? A day? A minute?). The idea was scrappeyrjöperskelesd before the end of the first season. This was {{Lampshaded}} in a later episode when Ivanova stated that she was going to hold some troublemakers in custody for a Drazi cycle, after which the problems they were causing on the station would be sorted out. The Drazi she's explaining this to laughs, and points out that a cycle is a Drazi ''year'', not a Drazi month.

* In 2004, Switzerland and Germany wanted to build a [[http://de.wikipedia.org/wiki/Hochrheinbr%C3%BCcke bridge over the Rhine]], starting from both sides. To meet in the middle, they agreed to build it on a certain height above mean sea level. Unfortunately, the Germans measured in height above the North Sea, while the Swiss measured in height above the Mediterranean Sea, which differ by about 27 centimeters. The designers were aware of that difference, but subtracted it from the wrong side, leading to a final height difference of more than half a meter.

** The unit of ''weight'' (normal force) in the SI system is newton (N). One newton is one kilogram (mass) multiplied by gravity acceleration (9.81 m/s
), making a mass ot 1 kg weighing 9.81 N on Earth. The value 9.81 is close enough for 10, making conversions easy - just multiply by ten.

** In scientific literature, you may find references to the "pound-mass" to refer to that concept, abbreviated "lbm", mainly because the Imperial unit of mass, the slug, is stupid. Whether that particular convention is followed or not, though, is hit or miss.

** In scientific literature, you may find references to the "pound-mass" to refer to that concept, abbreviated "lbm", mainly because the Imperial unit of mass, the slug, is stupid. Whether that particular convention is followed or not, though, is hit or miss. The definition of slug is "the mass which accelerates by 1 ft/s2 when a force of one pound (lbF) is exerted on it." One slug has thus a mass of 32.174049 lbm or 14.593903 kg based on standard gravity, the international foot, and the avoirdupois pound. At the surface of the Earth, an object with a mass of 1 slug exerts a force of approximately 32.2 lbF or 143 N.


Added DiffLines:

*** Even more confusing is the concept of ''poundal'', which is force. The poundal (symbol: pdl) is a unit of force that is part of the foot–pound–second system of units, in Imperial units introduced in 1877, and is from the specialized subsystem of English absolute (a coherent system). 1 pdl = 1 lbm⋅ft/s^2 The poundal is defined as the force necessary to accelerate 1 pound-mass to 1 foot per second per second. 1 pdl = 0.138254954376 N exactly.

** The units of ''energy'' (distance multiplied by force) and ''torque'' (distance multiplied by force), but they are different products. Energy is ''scalar product'' while torque is ''cross product'' (matrix product). Thus while the unit of both are newtonmeter in SI system, the unit of energy has its own name, joule (J): 1 J = 1 Nm. The unit of torque is newtonmeter, but cross-product (N x m). When you lift a weight of one newton up one meter, it is energy of one joule; when you pivot a lever, length of one meter, by force of one newton, it is torque of one newtonmeter).

* The most famous example of all: Han Solo bragging that his ship can make the Kessel Run in "less than twelve parsecs". Parsecs are a unit of distance, not time. While this has been {{Retcon}}-ned to death with constantly shifting backstories about skilled pilots shaving distance by flying close to black holes, even those omit that the parallax second is based on local (terrestrial) factors, specifically the radius of the Earth's orbit, [[TranslationConvention and would have no meaning in "a galaxy far, far away"]].

** In a rather literal meta-example of this trope, there was much confusion over the definition of the term "unit" from ''AttackOfTheClones'' (referring to the two hundred thousand units being ready and a million more well on the way). Many assumed it referred to a military unit, and [[FlameWar took issue]] when it turned out to refer to [[SciFiWritersHaveNoSenseOfScale an individual clone]]. The thing is, it had always referred to an individual clone, even before the movie came out as the ''AttackOfTheClones'' movie novelization (which came out about a month before the movie did) [[AllThereInTheManual pretty much told us that "unit" referred to a unit of production]], and matched the "million more well on the way" statement with "a million clone warriors".

* In the second ''Film/{{Taxi}}'' film a policeman's French dialogue indicates that the protagonist's souped-up taxi was traveling at '200 kilomètres à l'heure' (200 kilometers per hour). In the English subtitles this is [[BlindIdiotTranslation blindly translated]] as '200 miles an hour'. It has no bearing on the plot but it credits the vehicle as going much faster than it really is (124 miles per hour).

* Metric confusion is the origin of the main character in ''WesternAnimation/JimboAndTheJetSet''; the aircraft company confused inches and centimeters, resulting in a less-than-jumbo jet.
