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 A system is superior to any american shenanigans!
A4 paper size FTW!
2xA5=A4
2xA4=A3
2xA3=A2
2xA2=A1
2xA1=A0 = 1 m²
And the ratio between sides is √2
It’s beautiful
