minus-square@subtextlink5•edit-23 months ago The redefinition of the mole in 2019, as being the amount of substance containing exactly 6.02214076×10^23 particles Since the 2019 SI redefinition, avogadro’s number is a constant. https://en.wikipedia.org/wiki/Avogadro_constant Edit: looks like we were both right! I was reading through your link and it seems the work reported by the NIST led to the exact definitions for Avogadro’s number and the Planck constant.
