Off-topic, but in defence of non-metric units, dividing by 3, 2, 4, etc. is not really a problem. The old units like old UK money were difficult because they mixed several bases (20, 12, and 4, as well as 10). Time, of course, still mixes bases 60, 24, 7, and 10, as well as base 365/365-and-a-bit. Metric is unfortunate in using base 10, which is really a bad choice for everything, even counting fingers. Base 12 is divisible by far more useful things, base 18 wouldn't have been too bad, and base 16 would have made IT easier. But change is out of the question now, it would be like inventing esperanto.
