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 haven’t had to think twice about 32F being the freezing point since before I could drive. It’s just one of a thousand numbers I can remember. There’s no particular advantage between g being 9.8m/s/s or 32ft/s/s. Nothing round about pi being 3.14. Whatever you use becomes recognizable quickly. My car takes 87 octane gas, takes 5w30 oil, has a wheel bolt pattern of 5x108mm or 5x4.25in, has a 63.4mm center bore, 320mm front brake rotors… The list goes on.
