I now wish we'd have gone "hard metric" back in the late 70's, when Jimmy Carter was pushing for it.
I'd probably need a few hundred less wrenches and sockets.
Half the stuff I work on is metric, and half SAE. Big pain it the caboose.
I worked at a liquor store when that industry changed over back in the early 1980's- we all lived thru it.
Except beer is still in 12 oz containers.
