It survived as the Byzantine liquid ounce (Ancient Greek: οὐγγία, oungía) and the origin of the English inch, ounce, and fluid ounce. The Roman inch was equal to 1 ⁄ 12 of a Roman foot (pes), which was standardized under Agrippa to about 0.97 inches or 24.6 millimeters. [citation needed] The Roman ounce was 1 ⁄ 12 of a Roman pound.

An ounce-force is 1 ⁄ 16 of a pound-force, or about 0.2780139 newtons. It is defined as the force exerted by a mass of one avoirdupois ounce under standard gravity (at the surface of the earth, its weight). The "ounce" in "ounce-force" is equivalent to an avoirdupois ounce; ounce-force is a measurement of force using avoirdupois ounces.
A metric ounce is an approximation of the imperial ounce, US dry ounce, or US fluid ounce. These three customary units vary. However, the metric ounce is usually taken as 25 or 30 ml (0.88 or 1.06 imp fl oz; 0.85 or 1.01 US fl oz) when volume is being measured, or in grams when mass is being measured.

In the 18th century, the table-spoon became an unofficial unit of the apothecaries' system of measures, equal to 4 drams ( 1 / 2 fl oz, 14.8 ml). It was more commonly known by the Latin name cochleare majus (abbreviated cochl. maj.) or, in apothecaries' notation, f℥ss or f℥ß (fluid ℥, i.e. ounce, semis, one-half). [13] [14] [15]
BuzzFeed collected McDonald's cups from different countries to see just how they compared -- and (un)surprisingly, cups in the USA were the biggest by far. In America, a small drink is 16 oz., a ...
The atomic mass constant, denoted m u, is defined identically, giving m u = 1 / 12 m(12 C) = 1 Da. [ 3 ] This unit is commonly used in physics and chemistry to express the mass of atomic-scale objects, such as atoms , molecules , and elementary particles , both for discrete instances and multiple types of ensemble averages.
An imperial fluid ounce is 1 ⁄ 20 of an imperial pint, 1 ⁄ 160 of an imperial gallon or exactly 28.4130625 mL. A US customary fluid ounce is 1 ⁄ 16 of a US liquid pint and 1 ⁄ 128 of a US liquid gallon or exactly 29.5735295625 mL, making it about 4.08% larger than the imperial fluid ounce. A US food labeling fluid ounce is exactly 30 mL.
