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.
The only reason I prefer Freedom Units is because that’s what I’ve grown up with and know. If I had grown up using metric, I would choose that all day. It just makes more sense, there’s no random “12 inches to a foot” or “16 tablespoons to a cup” (I had to look this one up).
Metric is easy. A decameter is 10 meters. There are 10 decimeters in a meter. Each step up or down is 10 of the previous.
I know it’s not nearly as easy as 10s, but I always think of Freedom Unit liquid measurements in 4s.
1 gallon = 4 quarts (the name kind of gives that one away) 1 quart = 4 cups 1 cup = 4 quarter cups (yeah yeah, I know. Duh. But wait…) 1 quarter cup = 4 tablespoons
And then teaspoons have to be little assholes and throw the whole thing off, but whatever.
