Move over Le Grand K, the Planck Constant is the hot new basis of mass and other derived measurements!

quote [ Updates to scientists’ system of measurement went into force May 20, redefining the kilogram and several other units in the metric system. The revamp does away with some outdated standards — most notably, a metal cylinder kept in a vault near Paris that has defined the kilogram for 130 years. ]

Happy belated World Metrology Day!

It'll be interesting to watch Big K from now on and see how it drifts. It's been suspected for a while now that's it's been changing, hence why the new definition is a big deal, but by definition there was also no way to objectively quantify it.
