The only thing that would be better than switching to the metric system would be if we could switch to a base 8 or base 12 numbering system and then use the equivalent of the metric system. Base 10 sucks. Base 12 for the win! US measurements make sense if you do fractions as they are base 12 or base 16 (lots of common factors). If I had to do everything metric I'd need a calculator. Fractions I can do in my head easily. Man I HATE decimals. IIRC Japanese builders are dropping metric for "traditional" measurements for the same reasons.
