Fair enough Jim, Ezra. I concede this. I will point out though that in metric countries old unit names are sometimes retained (informally) but they refer to rational metric quantities. For example the pint (in various langages) is still spoken of in Continental Europe but actually means half a litre, as does 'pound' (pfund etc) refer to 500 g. Phil
