We have a nice mixture of both here in the good old USA... Its ALWAYS been a mixture of metric/inches wrenches when you work on any car or motorcycle here... and on some cars with the digital dash for fun you can always hit the switch from MPH to KMH when your buddies aint looking and say "damn... look how smooth the rides going over 100"
We buy our milk and gas by the gallon and our Cokes by the liter...
But one form of measurement will NEVER change... when your wanting absolute precise zero tolerance NASA approved perfection... the RED CUNT HAIR is the WORLD standard!!!
