** A potion has no appreciable weigh, neither does acid, holy water or [[GreekFire alchemist's fire]]. But a potion vial (the sort of thing that they are in) does. Therefore liquids in [=D&D=] have negative weight.

* ''Film/TheWizardOfOz'': The infamous "Sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side." mangling of the Pythagorean theorem, as said by the scarecrow after he got his brain. It should be, "The square of the hypotenuse of a ''right'' triangle is equal to the sum of the squares of the other two sides." (Of course, since the Scarecrow hasn't actually had any real increase in intelligence or learning, this could be intentional; he thinks he's now clever, so he says something that ''sounds'' clever). This is lampshaded in ''WesternAnimation/TheSimpsons'', where Homer says the exact same line in an attempt to sound smart after putting on Henry Kissinger's lost glasses, and a person in the bathroom yells out, "That's a right triangle, you idiot!" Homer then responds to this with [[CatchPhrase "D'OH!"]]. The French dub of the film (titled Le Magicien d'Oz) averts the mistake, where the Scarecrow says "La somme de l'hypoténuse au carré doit être égale á la somme des deux cotés opposés au carré", or "The square of the hypotenuse must equal the squares of the two other sides" in English.

** In ''Chamber of Secrets'', Ginny mentions wanting to attend Hogwarts ''since Bill came''. Bill went to Hogwarts a year after Ginny was born (and that's without the earlier dates from the paragraph above). So Ginny wanted to go to Hogwarts ''since she was one''? Or ''before she was born''? It was also unnecessary because she has 4 older brothers she would've been able to bond with before they went off to Hogwarts. (Of course, she wasn't exactly thinking clearly at the moment.)

** This may be intentional, Wailord is based on a blimp and as such has high HP and low defense so it would make sense that his weight is far smaller than his size, he's a balloon.

You have just discovered the fundamental truth: that your favorite author failed irredeemably at high school math and never wants to see a number ever again except in the corner of a page. This is a particular kind of continuity error that would be avoided if professional writers kept calculators at their desks. In their defense, some of these mistakes can be obscure and noticed only by die-hard fans. It can also come from multiple writers not checking with each other, or screwups in the timeline.

Oh, for the examples below that reference the number Pi, it is an irrational number with no limit -- an endless number -- of digits, but the first 12 are 3.14159265359.[[note]]Note that they're rounded -- the first 12 digits are 3.1415926535'''8''', and the next digit would be a 9, so the 8 is rounded up.[[/note]]

** They also believe that 3.86 Terajoules is more energy than what the Sun contains. For comparison's sake, Little Boy, the nuke that exploded over Hiroshima in 1945, released roughly 16 times more energy (63 Terajoules).

Added DiffLines:

** Ironically, that entire episode is about Phil making a boneheaded math error--he thinks a "family curse" will cause him to die when he turns 81, but Arnold eventually realizes that all his predecessors died when they were ''91'', not 81. Apparently the writers can do math, but didn't quite think everything through.

* ''Film/MammaMia'' has a real doozy; it is set in the modern era, as the clothing of the main characters and a line about a "web site" would indicate. At the ''earliest'' it would have to be set in about 1998, when advertising your business via the Internet became a thing. The film revolves around a 20-year-old girl trying to find out which of three men is her birth father, meaning she would have been conceived, again, ''at the earliest'', in 1978 (but probably as much as a decade later, as nothing indicates the film isn't set in the same time period as when it was released, in 2008). However, many lines of dialogue, and one song, indicates that her mother met these three men during the early to mid-sixties (Creator/PierceBrosnan's character dressed like a hippie when younger, plus Stellan Skarsgaard's character out-and-out states that "those crazy years, that was the time of the flower power"). This is also consistent with the fact that Meryl Streep, Christine Baranski and Julie Walters play "childhood friends" who were apparently also a short-lived singing group ''in the sixties'' meaning that they would have had to be at least in their late teens by then, and all three of them (and all three of the potential fathers) appear to be somewhere in their mid- to late-fifties. Not just appear; they refer to each other getting "old", and at one point Baranski refers to Walters as a "senior citizen". Okay, so maybe Streep's character was impregnated later in life. Nope; repeated dialogue has her in her late teens when she got pregnant. So, to recap: Streep, as a young girl in her late teens in the early to mid-sixties, was in a singing group at the time, and met three men, one of whom impregnated her...with a daughter who is still twenty years old in either the late 90s, or (more likely) somewhere around 2008!

* ''Series/TwentyFour'': The first season takes place "two years to the day" after Jack Bauer led a covert strike in Yugoslavia during the 1999 Kosovo War. It is also a presidential election year. [[note]]Presidential elections in USA are held four years apart, and the count started in 1788. You can't ''have'' a presidential election in 2001; the writers either missed the 2000 elections or anticipated the 2004 ones. Or, like ''Series/TheWestWing'', ''24'' takes place in an alternate timeline in which the elections occur on a different schedule.[[/note]]
