People use stone for weighing people, anything else is usually measured in kg. Trust me, I'm an Engineer, we specialize in pedantic, boring details like this. Using imperial units is rather unscientific.

That's what I meant by my post. I do not believe I've ever seen Stone being used for much else, all else is Kg or appropriate metric unit (or imperial one, in certain cases.)
