"Nearly 50 years ago" was the US made an effort to go metric. People thought the transition would be "soon". Highway signs were put up in both metric and miles.

I suspect that that was the high point in teaching metric in schools.

There's a difference between knowing metric and really having a feel for it. I speak as someone trained in physics, but that doesn't mean I had a real sense for what it means. What clothes should I wear for 23C weather? Is 13mm of rain in an hour heavy or light? Is a car which consumes 4.5L/100km one that is fuel efficient compared to most? How many centimeters tall are you?

Even now, living in a metric country for years, I have to think about some of these by translating into, say, 52 mpg.

It is a lot more difficult than folks think, that's for sure. I've only been living in a metric country for 3 years, and I am only beginning to get a feel for these things. Congratualations, me, you can no longer describe some bits of life and the world in relatable terms.

Here's a fun one the other way. I know what 80-100C means as sauna temperatures, and I prefer around 90C, but have to do some math to figure out that's 175F-212F, and I prefer around 195F.

(Okay, the 100C=212F is a gimme, but not the others.)
