and not so hard to convert
“Please change the entire world’s system to make it easier for the one country that uses a different one”
It wouldn’t even change the difficulty, really. You’d just wind up multiplying or dividing by 9/10 instead of 9/5.
America moving zero to Celcius’ zero would be better, it would remove one whole step from the calculation
Then if they made their degrees about 9 fifths the size (they could get higher resolution than they’d lose by doing what we do and quoting temperature to one decimal place where needed) it would be dead simple to convert (just change the symbol from °F to °C!)
Celsius is literally just Kelvin but shifted… So it’s just as friendly for “universal math”.
