Even France used pounds (livres) before the Revolution, i.e. in the middle ages.

... having said that, I guess that, if D&D had been developed outside the English-speaking world, it would probably use metric units regardless.

While we're on the subject, when are you'se switching to metric like the rest of the world!? How heavy is a pound? Is it an imperial pound or an american pound? Is there a difference?

There's no difference, but come on, this is a fantasy setting. Maybe Galt, like revolutionary France, uses some sort of decimal system of measures, but otherwise it just isn't setting-appropriate.
