0°F is the coldest night Mister Fahrenheit has ever witnessed, thinking it couldn't become any colder than this.
100°F is Mister Fahrenheit's slightly feverish body temperature.

PS: Pretty much all other countries also had their own measurement systems and simply switched to metric because it made sense. I'm glad we did, and that pretty much all others did too.
PPS: I'd also be up for revamping time measurement, why can't we have 10h a day, 100 minutes per hour, 100 seconds per minute? 100.000 seconds in total per day, currently we have 86.400 so a second would only become slightly shorter.
The French tried to implement that in the First Republic, together with 12 months à 30 days per year, 3 weeks à 10 days per month and 5 (6) extra days at the end of the year to make it work (from Christmas to New Year, how thematic!)
It failed because the French were fearing they'd have to work more (if they'd also only have 2 days off per 10d instead of per 7d). One of the biggest tragedies in French history. Without the week reform the time reform might've succeeded.
I love it when it's -10% hot in winter nights or 110% hot around the equator. Makes perfect sense.
