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.
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.

Iirc the Joule is favoured over the Calorie in the SI system.
Is that something people wonder about? I doubt it.
It’s not like physicists, chemists or engineers are a thing.
They are in fact 3 things
I’m glad you admit yourself it’s not a thing

Oh, I love these freedom units
