I think Dave will appreciate this most ...

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.

Cheers,
