alt Hacker NewsOddly enough as a person born in a metric country, now living in Canada which is metric, and always educated in metric, I agree with you on the feet and inches. "A couple of inches" doesn't imply nearly the precision that "5 centimeters" (using the US spelling on purpose) implies. Similarly my own height of 5'10 is much more "human scale" than the 178cm that it says on my passport.
Not for engineering though!!! Being able to add 1/64 and 5/16 and 17/32 etc. in your head without stumbling is a skill that I did not acquire.
Don't agree on the Fahrenheit though and for the same reason! Degrees are just the right scale, and besides, anchored at freezing (0) and typical boiling (100) points. But that's just habits. Probably if I'd grown up with Fahrenheit, I'd prefer it too. And besides the oven defaulted to Fahrenheit and we never changed it. 350F...
And I would come the opposite conclusion to you.
On Fahrenheit, the Americans are surely right. For describing the weather, a system where the usual range is 30-100 is clearly more useful than one where it's 0-37, because you can say "high 70s" instead of the weirdly specific "about 27", and "low 40s" instead of the awkward "around 5 to 7".
I say this as a European who has never used Fahrenheit.
