Haha. Also I guess because the larger unit makes for easier comparison. For example, while we in the UK we still habitually use imperial measures to weigh ourselves rather than metric, we don't know our weight in pounds, but in stones and pounds, which gives a more manageable/comparable number. It's so habitual to do that, that many people (including me) can't easily do the mental maths conversion to a US-style imperial weight at all. It still enrages me that there are 14 pounds in a stone but 16 ounces in a pound. What kind of system of logic is that?
