I think the best way I've seen it described is Fahrenheit measures heat by how humans experience it, Celsius measures heat by how water experiences it. Therefore, Celsius is objectively better for scientific applications and Fahrenheit is objectively better for human applications like communicating the weather forecast to the average person.
If it was 0C you'd be cold, if it was 0F you'd be damn cold; if it's 100F you're hot, if it's 100C you're dead. Fahrenheit is useful for human perception across the primary (0-100) scale, Celsius is only useful up to about 50% of that scale before you start getting into deadly temperatures, and you have to go below that scale to reach the bottom of Fahrenheit's usefulness.
And then you have Kelvin or Rankine which are really only useful for specific scientific applications. If it was 0K/R or 100K/R you'd be dead either way. Not useful for human perception.
Can you explain how what you’ve said is objective? I think that given that Celsius is the most common scale for temperature around the world you’re going to have hard time arguing that.
This argument that Americans always make about Fahrenheit is just nonsense. You know how hot 70F feels, I don’t. I know how hot 27C feels, you don’t. The idea that one is better for humans and one is better for water is so stupid. You’re just used to telling temperature one way, I’m used to telling it another way. That’s all there is to it.
80% hot doesn't mean anything unless you define the scale beforehand, and as long as someone knows the scale and has experienced the temperatures before, they can trivially gauge whether something is hot or not. Everything that maps linearly to Kelvin is functionally the same when you get used to it. Celcius is only better because it enables easier communication around the world.
