Well, okay, they changed Kelvin and Celsius at the same time, so that 273.15/273.16 are preserved, with Celsius based on Kelvin instead of the other way round.

But when you're dealing with the freezing point of water and the old version of Celsius for simplicity, then those numbers aren't as correct as they used to be.

They're not far off, especially near the triple point of water: https://www.bipm.org/documents/20126/2619564/Estimates_Diffe...
