It’s just designed with a slightly different set of assumptions.
Instead of water freezing and boiling 100° apart, it’s 180° in fahrenheit. That makes it so that they’re on the opposite sides of a temperature gauge, and a degree of rotation of the gauge matches a degree of temperature.
Instead of zero being the freezing point of water under specific conditions, it’s a brine solution whose temperature will stabilize in a way that’s useful for using as a calibration point.
Stripped of its context, it’s odd. But it’s not irrational, just no longer consensus as the standard, and as such deprecated.
Never. They use the same spacing between degrees. The Kelvin scale was derived from the Celsius scale, just placing the 0° at absolute zero rather than at the freezing point of water.
Fun fact time, -40F is -40C.
And 575F is 575K
Fahrenheit is a strange scale.

And at what temperatures are C and K equal?
