My point is “really hot” and “really cold” are not useful reference points to ascribe to, no matter what numbers you’re using. If i was coming up with a measurement system for brightness and i said 1000 was “really bright” would you be able to tell me anything about 500? No because you literally have no reference frame for what i mean by “really bright”. It’s the same thing when Americans describe Fahrenheit to the rest of the world. You have to experience the data points, and at that point, whether you use 0 to 100, -20 to 40, or 250 to 310, it doesn’t matter. You will just intuitively understand the scale and so there’s no inherent benefit.
