the title says it all. me, i use metric. i am biased, but imperial makes no sense with 14 pounds to a stone and some other random number for a tonne or whatever is next. also, meytric has things like millimetres, centimetres, metres, kilometres, miles, ect. with all but one having a commen suffix and a logical order of prefix's. also, it is all in 10's, 100's, 1000's ect so again it stikes me as more logical. prove me wrong tfw users.
