New kilogram could have mass appeal, say scientists
You won’t feel it happen, but the kilogram, used to measure the mass of electrons, galaxies, and everything in between, is about to be transformed.
The General Conference on Weights and Measures is set to meet in Versailles, France, in November to vote to redefine the kilogram in terms of a fundamental physical constant, Planck’s constant, making it the final metric unit to be uncoupled from a material artifact.
