Uncia (unit)
From Wikipedia, the free encyclopedia
An uncia (plural: unciae) is an ancient Roman unit of length that roughly corresponds to an inch. One uncia is 0.97 inches or 24.6 millimeters. There are twelve unciae in one pes, another Roman measure of length.
The words inch (1/12 of a foot) and ounce (originally 1/12 of a pound and still 1/12 of a troy pound) are derived from the word uncia.
