Re: Le Grand K's fate
So what's going to happen to Le Grand K?
Nothing much. Greengrocers won't suddenly sprout Kibble balances in the back rooms of their shops; you still need practical artefacts to calibrate stuff against, with the Grand K (and its copies around the world) continuing to sit at the top of that pyramid - it's just that instead of being exactly 1kg by definition it will now simply embody a reference kg with a measured and documented (tiny) error.
