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.
Weight of human beings, weights at the gym, etc.: pounds
Height of people: feet and inches
Height of buildings: mostly feet, but occasionally meters.
Depth of water in scuba: meters
Kitchen weight: grams
Kitchen volume: fluid ounces only between 0-128 oz, then gallons after that. Decimal places, not fractions. So for example, cocktail recipes should all be in ounces, no tablespoons or teaspoons.
Distances in wilderness: meters/km
Distances on a football field: yards
Distances on a basketball court: feet
Distances on roads or in cities: miles
All temps in Fahrenheit.
