21F is just jacket weather.
Only if it’s windy and cloudy. A calm sunny day at 21f is fine for walking around in shirtsleeves.
Depends on how acclimated you are. Right now, for me, I’d be freezing, but if you caught me when I lived in North Dakota, sure.
Fun fact, -40C and -40F are the same temperature.
Then 575K and 575F are the same.
Also -40C / -40F and 575K / 575F is the temperature of the center and edges of a hot pocket.
I hate to be the good time ruiner, but unlike -40, it’s not on the nose.
Still, really cool that it’s as close a conversion as it is.
So you’re saying, that we should switch to specifying every temperature as a nice 69 and just switch out the unit?
69C° is just sauna
Nice.
