The ounce (/ˈaʊns/) is any of several different units of mass, weight, or volume and is derived almost unchanged from the uncia, an Ancient Roman unit of measurement.
The avoirdupois ounce (exactly 28.349523125 g) is 1⁄16 avoirdupois pound; this is the United States customary and British imperial ounce. It is primarily used in the United States to measure packaged foods and food portions, postal items, areal density of fabric and paper, boxing gloves, and so on, but it is sometimes also used elsewhere in the Anglosphere.
Although the avoirdupois ounce is the mass measure used for most purposes, the 'troy ounce' of exactly 31.1034768 g is used instead for the mass of precious metals such as gold, silver, platinum, palladium, rhodium, etc.
The term 'ounce' is also used in other contexts:
The ounce-force is a measure of force (see below).
The fluid ounce is a measure of volume.
Historically, a variety of different ounces measuring mass or volume were used in different jurisdictions by different trades and at different times in history.
