Uncia
The word uncia was Latin for a unit equal to 1/12 of another unit called the as. The words ``inch'' (1/12 of afoot) and ``ounce'' (originally 1/12 of a pound and still 1/12 of a ``Troy pound,'' now used primarily to weigh preciousmetals) are derived from the word uncia.See also Calcus, Half, Quarter, Scruple, Unit Fraction References
