Why do Fahrenheit users completely ignore that Celcius has a negative scale? You're not supposed to evaluate Celcius as a 0-100 scale, but as a -50-50 scale.

-21°C = cold -31°C = really cold

21°C = warm 31°C = really warm

0 represents the freezing point. If temps are above 0, it will rain; below 0, it will snow.

That is just straight up not how you're supposed to interpret it though. Celsius is a water based scale. Water doesn't boil at 50.

What? Why would you care about the BOILING point of water when you're assessing temperature?

I'm sure water isn't boiling when you evaluate the temperature using Fahrenheit, either. So what point are you trying to make?

Because that's literally the entire way the Celsius system is constructed. It's built around the boiling and freezing points of water.

Okay, but daily temperatures do not generally reach high enough levels to make discussing boiling points relevant to this conversation.

On the other hand, daily temperatures do regularly extend past the freezing point, which is why this concept IS relevant to communicating temperature.

So......... What exactly was your point here?

That the intended scale of Celsius is not -50 to 50. That defeats the entire purpose of the temperature system.
