> trade in Imperial measurements with the US The US doesn't use the Imperial system but it's own customary system. For example, the Imperial pint is about 568 mL, whereas the US customary pint is about 473 mL (liquid pint) or about 551 mL (dry pint). Both are 1/8th of a gallon as defined in each respective system. (notice how I conveniently included the metric equivalent of both measurements?)
