You know, I find the old line that "there are two types of countries: those that use metric and those that have walked on the moon" very amusing, but we got to the moon using the metric system! It just makes a lot more sense, and although daily life has been done in the US with our standards of measurement just fine, I do think it would make sense to convert. Sharing the same standards as the rest of the world would make things easier. The part I think I would have the most trouble with is Celsius--there's no simple way to understand that, you just have to throw Fahrenheit in the trash and start over like a baby. The only shame would be that Fahrenheit 451 sounds a lot cooler than Celsius 232.778.
