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 have my phone set to show me the temperature in Celsius. I've tried really hard to internalize how far a kilometer is, and have failed so I still have my distance units set to miles.
