    Some people will use some letter salad just to avoid the imperial system /s

      In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade—which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it. Whereas in the American system, the answer to ‘How much energy does it take to boil a room-temperature gallon of water?’ is ‘Go fuck yourself,’ because you can’t directly relate any of those quantities. (John Bazell)

        Unfortunately converting 1 calorie to joules ruins everything 4.2J per calorie. Makes it annoying to calculate how quickly you can boil water for instance.

        ‘How much energy does it take to boil a room-temperature gallon of water?’

        Is that something people wonder about? I doubt it.

          A BTU (British thermal unit) is the energy required to raise 1lb of water 1 degree Fahrenheit…which may actually be even dumber, since it’s temperature sensitive to begin with. Dumbest of all, the Brits don’t use that unit very often. The US, and, I assume, Liberia use it all the time.

      Don’t imperial have like 3 different letter sizes depending on the country?

        From what I have found, the US has 216mm × 279mm while Canada has 215mm × 280mm which is close enough.
