See, to me, the metric system makes a LITTLE sense. I mean, not the distances (a meter? what the..? It uses a distance arbitrarily set at a fraction of said distance originally). But temperature (water freeze, water boil as the "endpoints) does make sense. Time is kind of screwy too, using radioisotope frequencies... but, yeah, whatever. Have to use something as the benchmark. Weight and volume are too interbred for my taste, but it makes conversion in one's head easier (1 liter of water is 1 kilogram)

I dunno, I guess it helped in science class, with the math. But there's too many fractions in everyday life for it to be practical. Really, why does a meter have to be used, when most things are fractions of a meter? Use a smaller measure as your standard unit.

Despite a college science major, a graduate science degree and a lot of science in high school, I still can't convert temperatures. But why'd the world have to change, instead of adopting the system used for centuries?
