Originally one kilo was the weight of one litre of water at O°C. That was more understandable, but also rather imprecise.

Don't think so. Quote from the article at the provided link: "That won't make any perceivable difference to most people's lives at all . . ."

We have to buy new scales first.  I think the evil multinational  gram-scale conglomerate is behind this outrage.  Just when you've weighed all your coins in old grams, Boom, they hit you with this.

Let's go back to using "grains"!  Who's with me?!?

I'll just buy an old-style balance and weight my coins against a Planks' constant of caesium atoms.  Looks simple enough......
