The Germans (and I’d guess other Europeans as well) are kinda nuts about the metric system. So much so that they even sell eggs in cartons of ten. Who knew…
Actually, I think the metric system makes a whole lot of sense, and can’t understand why the US didn’t follow through with the push to convert back in the ’70’s. I’m kinda getting the hang of it, but measuring speed in kilometers per hour is still kinda weird to me. As is temps in Celsius… Seems like kind of a foreign language in a lot of ways.
