It's not really identical though. Like I said, Fahrenheit is higher resolution at these scales so that is an advantage. It doesn't mean everyone should convert to F. Just that both systems have benefits. If I changed my perception of the world to C I wouldn't actually gain anything, personally, in the context of weather and HVAC.

If I need to take measurements while boiling water or making ice then I would probably use C.

It's exactly the same. The perception you have on Fahrenheit is exactly the same anyone using Celsius have, with multiples of 5 instead of 10

Five is not equal to ten so no, it is not the same. That's the entire point.

Right.
