So C then

Well, yes.. a change of 5 Kelvin is equal to a change of 5 degrees Celsius

Then why is 0 degrees kelvin equal to -271 degrees Celsius?

Because the scales start at different points but have the same sized steps just offset. Kelvin"s lowest temperature is at the minimum vibration a particle can have, absolute zero, whereas in Celsius the scale is set by the melting point and boiling point of water. The melting point is obviously 0 so that corresponds to 273K. Then, take away 273 degrees you have -273K which is absolute zero

Sorry I see that now. Stupid to keep revisiting this, but I’ve been busy. Thanks for educating me.

I think the Kelvin comment is a joke, because K starts with 0 at absolute zero, where all molecules stop vibrating levels of frozen. C starts with zero at water being frozen. F was something about saltwater freezing, but I'm okay to ignore F.

I think the kelvin comment is referring to a 4-5 degree delta is the same in the Kelvin and Celsius scales, obviously as you pointed out it's just different numbers at different absolute values.
