Would their demise mean they "can't have been that useful?"

We should keep the Imperial system, which is "an unfortunate result of trying to put the Anglo-Saxon distance units into the Roman-based system", and the "aberrant British units". Or do you propose to eliminate all units that come from Britain and just keep the God-given American system, which has been given to us not by Brits but by Native Americans?
