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.
Sadly, the US system is not the same as imperial. As far as I know the main difference is the gallon.
1 gal. Imp. = 1.201 gal. U.S.
I also hate having lb.f. and lb.m (pounds force and pounds mass), which have different units and at sea level are different by a factor of about 32).
