I doubt that there is a single American pound, any more than there
is a single African one.

However, in the USA, a pound is a derivation of an Imperial pound and,
in the UK, a pound is a metric pound. Since about 1950.

So you're saying there are 2 pounds to the Kg, and not 2.2 then? That's a
bit more difference than " for practical purposes, not at all" You're not as
sure as you were earlier are you?
