What the hell are you talking about. If it's 0°C outside (or below that), I know that it's high time to put winter tires on because the water in the puddles will freeze and driving on summer tires becomes risky. I had to look it up, but apparently that's +32 °F. Good luck remembering that.
+10°C is "it's somewhat cold, put a jacket on". +20°C is comfortable in light clothing. +30°C is pretty hot. +40°C is really hot, put as little clothing as society permits and stay out of direct sun.
Same with negatives, but in reverse.
Boiling water is +100°C, melting ice is very close to 0°C. I used that multiple times to adjust digital thermometers without having to look up anything.
It's the most comfortable system I can imagine. I tried living with Fahrenheit for a month just for fun, and it was absolutely not intuitive.
