Actually the US is more metric than you think. Catapillar almost went under and changed. Some recent american cars that I've helped kids work on need metric wrenches. When you are the only real holdout it means if you want to export you have to do it in metric.

My distances except for Kilometers I still think of in feet and inches, chains and rods, and acres. But if I say something about a yard and a half away my kids, from 30 to 18 look at me like I'm nuts. Even my 80 year old parents talk temps in degrees C.

Give'em a centimeter and they take a kilometre doesn't sound the same.

Once a month we get something in the news about an American running up the main highway at 100 Miles an hour, not seeing the km behind the thing. I think they know, it's just the excuse.
