As a unit of weight, the ounce derives from the Roman uncia (meaning “twelfth part”), which was 1/12 of a Roman foot or ounce. The standard or physical embodiment of the Roman foot, a copper bar, constituted the Roman pound standard and was divided along its length into 12 equal parts, called unciae. Thus, uncia designated both a unit of weight and one of length and is the source of the modern terms inch and ounce.* * *
