Comic strip of a ghost and a person with the American flag pasted on the head. The ghost repeats "Boo!" in the first three panels without getting any reaction, but when it in the fourth panel says "kg, cm, km, °C" the American gets scared and screams "AHHHH!!!".

Below 0 C? Freezing doesn't mean dangerous (obviously it's dangerous if you're homeless or don't have regular access to heat). I live somewhere now that it hovers around freezing all winter and I literally can't wear my old thick coats from where I grew up (northern US). I have to wear a fall coat pretty much all winter or I overheat. Below 0 F is a much better indication of dangerous weather than the freezing point.
How about just slipperyness? The fact that you can't farm and thus have no reliable food source? The fact your water souce disappears?
I'll admit, no method of measurement is perfect as biomes changes too drastically. This doesn't mean Fahrenheit is better though. It's not more intuitive, it's not better at actual measurements, and it's not as accepted by society ('cause people way smarter than me did find Fahrenheit worse than Celcius (see any above high school science/engineering))
To explain the more intuitive, I am literally incapable of using Fahrenheit, and it means fuck all to me. Thus my intuition is incapable of using it, and thus Fahrenheit isn't naturally understandable. Granted, Celcius isn't either.
if 0-100 isnt intuitive, the scale was never the problem
