The imperial system, which is still used for some measures in the United Kingdom and other countries, is based on avoirdupois, with variations from U.S. customary units larger than a pound. The pound avoirdupois, which forms the basis of the U.S. customary system of mass, is defined as exactly 453.59237 grams by agreement between the U.S., the ...
15 oz tower = 6750 gr ≈ 437.4 g London/Mercantile pound 15 oz troy = 16 oz tower = 7200 gr ≈ 466.6 g Mercantile stone 12 lb L ≈ 5.6 kg Butcher's stone 8 lb ≈ 3.63 kg Sack 26 st = 364 lb ≈ 165 kg The carat was once specified as four grains in the English-speaking world.
[d] However, whereas the US gill is divided into four US fluid ounces, the imperial gill is divided into five imperial fluid ounces. Thus, while the imperial fluid ounce is 3.924% smaller than the US fluid ounce, the imperial gallon, quart, pint and gill are all 20.095% larger than their US counterparts. [e]
However, the names of all SI mass units are based on gram, rather than on kilogram; thus 10 3 kg is a megagram (10 6 g), not a *kilokilogram. The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes.
The former Weights and Measures office in Seven Sisters, London (590 Seven Sisters Road). The imperial system of units, imperial system or imperial units (also known as British Imperial [1] or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments.
C-19 [17] Thus one troy ounce = 480 grains × 0.064 798 91 grams/grain = 31.103 476 80 grams. Since the ounce avoirdupois is defined as 437.5 grains, a troy ounce is exactly 480 ⁄ 437.5 = 192 ⁄ 175 or about 1.09714 ounces avoirdupois or about 9.7% more. The troy ounce for trading precious metals is considered to be sufficiently approximated ...
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.
The US Food and Drug Administration (FDA) defines the "food labeling ounce" as 30 ml (1.1 imp fl oz; 1.0 US fl oz), slightly larger than the 29.6 ml (1.04 imp fl oz; 1.00 US fl oz) fluid ounce. [37] Several Dutch units of measurement have been replaced with informal metric equivalents, including the ons or ounce.
