I'm with you Roo, I LOVE my metric system that make sense all the way...
I try my best to adapt to the American "system" but it's not easy, everything's a mess and you actually have to learn each system one by one (weight, lenght, volume etc) Metric is sooo easy, just 1, 10, 100, 1000 on all types...And a metric ton is of course 1000kg :-)
