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.)
