One would assume the case of metric vs. imperial units to be settled once you lose a $ 327.6 million space mission to faulty calculations involving imperial units. Yet, I know staunch defenders of the imperial units system. This rant is for them (transcript follows):
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.
According to Reddit, the excerpt is from the book “The Secret Life of Violet Grant” by Beatriz Williams. Couldn’t have put it better.
