The U.S. is one of only three nations in the world (the other two being Liberia and Burma) which clings to its outmoded system of measurement, failing to get on board with the rest of the world and use the metric system.
We don’t even use the British Imperial system (that the British don’t even use anymore) – we use some bastard child of the Imperial system called “the United States customary system.” Ask any American how many ounces are in a gallon or feet are in a mile and you’re almost sure not to get a correct answer.
