We’re taught both metric and US customary units in school. I prefer metric for most things, to the point I have a metric-only tape measure among other things.
However, I’ll die on the hill that Fahrenheit is superior for ambient air temperature. 0 degrees to 100 degrees neatly encompasses the range of average surface temperatures seen throughout the year in the contiguous US.
I’m sure that’s mainly being used to one or the other? 0,5…0,75…1,5…2,5…4mm² are all quite distinct if you work with them a little. Imperials break my head though, can’t do all these fractions and conversions in my head.
I know what you’re sayin but AWG doesn’t use fractions. A good equivalent would be like shirt size. Small, medium, large, extra large. It’s just that size wire and that’s the end of it. You don’t need to know the diameter or cross section of conductor or whatever.
And even fractions are more of a feeling for us I guess. If you work with tools you can spot an inch, quarter inch, foot, etc. It really does come down to a “feeling” in a way that’s difficult to put in words.
