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 comfortable working in both systems, I prefer standard for furniture building because I need to divide by 3 or 4 more often than by 5. I’m also going to fly in knots, nautical miles and feet of altitude.
