I honestly am not sure what I made confusing. The definition I gave is the SI definition of Kelvin & Celsius since 2019. The formula I gave is more verbose than it has to be but it’s what you get when you expand it.
I’m not sure of the semantic difference. When I think “a meter is the distance travelled by light in X seconds” I think m = c/299792458 s, same with Kelvin.
Mixing unit definitions with formulae for things measured in those units is what’s confusing, I think. That equation doesn’t define kelvin, it defines temperature measured in kelvin.

From what I can tell, you’re using definition of the units? In that case K doesn’t equal that equation, but it is in units of that equation.
