Yeah, of course that is the case now that most definitions have been updated to be tied to physical constants rather than observations that rely on specific conditions…
But the same wiki article you linked literally says otherwise. The Kelvin’s magnitude was based on the magnitude of Celcius because of Charle’s Law.
I.e. the volumes of gases under the ideal gas law scaled linearly with degrees celcius by about 1/273rd between 0-100C - which led to the prediction that the lowest possible temperature a gas could be was -273C (because that would be the point where it theoretically would have absolutely zero volume).
Which is a long-winded way of saying stop being a smartass. The guy you replied to was just as technically correct as you were, given they said 1k stemmed from 1C.







Exactly, its just cope. Someone who grew up entirely on metric temperature will have exactly the same intuition. For example myself:
<0 = freezing 0-10 = Cold 11-17 = Warming up 18-24 = Comfortably warm 25-29 = Tropical 30-40 = Uncomfortably hot >40 = Dangerously hot
Besides which, all of this goes out the window once wind chill and other external effects that absolute temperature cannot account for come into play.
It’s the usual American exceptionalism that causes them to throw a tantrum every time they’re asked to conform to a worldwide standard. There’s a reason most of the world uses metric measurements for most things in every day life, and its because it just works once you get used to it.
