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.
In the apothecaries' system, which was widely used in the United States until the middle of the 20th century, [15] the dram is the mass of 1 ⁄ 96 pounds apothecaries (lb ap), or 1 ⁄ 8 ounces apothecaries (oz ap or ℥) [5]: C-7 (the pound apothecaries and ounce apothecaries are equal to the troy pound (lb t), and troy ounce (oz t ...
There is no international consensus on how much pure alcohol is contained in a standard drink; [2] values in different countries range from 8 to 20 grams (0.28 to 0.71 ounces). The example questionnaire form for the World Health Organization's Alcohol Use Disorders Identification Test (AUDIT) uses 10 g (0.35 oz), [ 3 ] and this definition has ...
In Canada, a teaspoon is historically 1⁄6 imperial fluid ounce (4.74 mL) and a tablespoon is 1⁄2 imperial fl oz (14.21 mL). In both Britain and Canada, cooking utensils come in 5 mL for teaspoons and 15 mL for tablespoons, hence why it is labelled as that on the chart. The volumetric measures here are for comparison only.
Troy weight is a system of units of mass that originated in the Kingdom of England in the 15th century [1] and is primarily used in the precious metals industry. The troy weight units are the grain, the pennyweight (24 grains), the troy ounce (20 pennyweights), and the troy pound (12 troy ounces). The troy grain is equal to the grain unit of ...
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
Such scales are used to make the most accurate of fine measurements, such as in the needs of empirical chemistry. Avoirdupois (/ ˌævərdəˈpɔɪz, ˌævwɑːrdjuːˈpwɑː /; [1] abbreviated avdp.) [2] is a measurement system of weights that uses pounds and ounces as units. [3][4] It was first commonly used in the 13th century AD and was ...
The tola (Hindi: तोला / Urdu: تولا, romanized: tolā; also transliterated as tolah or tole) is a traditional Ancient Indian and South Asian unit of mass, now standardised as 180 grains (11.6638038 grams) or exactly 3⁄8 troy ounce. It was the base unit of mass in the British Indian system of weights and measures introduced in 1833 ...
