The History of the Word
The word ounce, as a unit of weight, originated in the English language in the early fourteenth century. It comes from the Old French words once and unce, which are measures of weight or time. Those words are derived from the Latin uncia, which means “one-twelfth of a part,” and another Latin word, unus, which means “one.” These Latin words were adopted into Old English as ynce, which referred to one-twelfth of a pound in the troy system of weights (apothecary ounce), and one-sixteenth in avoirdupois (avoirdupois ounce). The abbreviation oz. comes from the old Italian word onza. In Middle English, ounce was also used as a measure of length (three inches) and time (around seven and a half seconds.) The Roman ounce also measured volume, area, weight, and length.
In apothecaries, the symbol ℥ was commonly used in place of oz to refer to the troy ounce.
