No it’s not.

What makes 0°F (-17,7°C) special for a human body? Is it the limit after which we don’t feel any colder? No.

And what makes 100°F (37,7°C) special? Maybe we can’t feel any hotter? No, we can. Is it the body temperature? No. What is it?

Maybe 50°F (10°C) is perfect? Nah, cold!

If we change 0°F to, say, 0°C and 100°F to 40°C, does it change the notion that 0°F is very cold for a human body and that 100°F is very hot? No, and as a bonus you get 50°F equaling that perfect 20°C.

Fahrenheit scale is super arbitrary and it’s hilarious when it is posed as a “human-centric” scale. At the same time, the concept of Fahrenheit scale is unnecessarily complicated and the notion between Celsius is extremely clear - you can easily calibrate Celsius thermometer with nothing but kettle and freezer, right at home, right now.

Also,

• Sub-zero Celsius = very cold, snow doesn’t melt, ice doesn’t melt
• 0 Celsius = cold, ice gets slippery
• 10 Celsius = jacket weather
• 20 Celsius = comfy
• 30 Celsius = hot
• 40 Celsius = scorching
• Above 40 Celsius = deadly, leave the area ASAP (short exposures like sauna don’t count). Also, fans stop cooling you down and now heat you up instead.

Simple enough.
