> There are good arguments to be made for everyday use of Fahrenheit over Celsius. The 0-100 range in F cover pretty much all of the temperatures one is likely to experience in the USA.

You're mostly right, but there are plenty of places in the US where the daily low temperature drops well below zero for significant parts of the year.

I guess the inconvenience with Celsius is that you're more likely to go to negative numbers? Is there a problem other than the having to say "minus ten degrees" vs "fourteen degrees"?

> It also has a finer resolution than degrees Celsius in everyday weather temperature ranges.

I'd make the opposite argument about everyday use. Most people I know would barely differentiate 25C from 26C, so there's not really a need for finer gradations. And the 10 degree increments are surprisingly convenient:

   -20 (or less)    dangerously cold
   -10 -- -20       damn cold
   -10 --  0        winter
    0  --  10       chilly
    10 --  20       brisk
    20 --  30       hot
    30 --  40       sweltering
    40 --  50       damn hot
    50 (or more)    dangerously hot

I like that table, and when I’ve been in Europe it’s pretty much what I’ve used. Oddly though while 30 degrees in southern Germany feels unbearably hot, 86 degrees in southern California is warmer than ideal, but not what I’d call scorching. I wonder to what extent it’s physical factors besides temperature and if there is a psychological effect from the temperature scales.

Humidity is a major factor. We cool our body below ambient temperature through evaporation cooling (sweat), which works much better in dry air.

From experience I'd say a sauna with 45°C and 80% humidity is about comparable with one at 80°C and 10% humidity.
