In 1893 the United States fixed the yard at ​3600⁄3937 metres, making the yard 0.9144018 metres and 1896 the British authorities fixed the yard as being 0.9143993 metres. ≈ 1.16364718615 US gal, ≡ 4 US dry qt system. Several of the units of liquid volume or capacity have similar names, but have different volumes – and in the case of fluid ounces and pints, different relations. ≡ 0.5506104713575 L, ≡ 40 imp fl oz The SI equivalents are quoted to four significant figures. The US customary system also includes the kip, equivalent to 1000 pounds force, which is also occasionally used as a unit of weight of 1000 pounds (most usually in engineering contexts). (See § Metric equivalents). This hundredweight is also called a short hundredweight. In particular, a new standard yard and troy pound were manufactured as the standards for length and weight respectively. American brewers package their beer in 12-US-fluid-ounce bottles, which are 355 mL each. The international yard is exactly 0.9144 metres.This definition was agreed upon by the United States, Canada, the United Kingdom, South Africa, Australia and New Zealand in 1959. The table of imperial avoirdupois mass is the same as the United States table up to 1 pound, but above that point the tables differ. Twenty hundredweights are one ton. The British imperial pint is about ​1⁄5 larger than the American pint because the two systems are defined differently. ≡ 31.5450982 US fl oz (food) The old Imperial system used 14 pounds. The yard is the only unit that has not really changed since that time. ≡ 0.25 US dry gal, ≡ 1101.220942715 mL ≡ 0.125 imp gal, ≈ 19.2151988081 US fl oz It consists of the Winchester bushel and its dependent quantities, the peck, (dry) gallon and (dry) quart. ≈ 0.107420875922 US dry gal, ≈ 19.3787794384 imp fl oz The US Customary system of units was developed and used in the United States after the American Revolution, based on a subset of the English units used in the Thirteen Colonies. The furlong and the acre have not changed much over the last thousand years either. Кликните, чтобы переключиться на русский. [79] Metrication is also all but complete in the Commonwealth countries of Australia, India, New Zealand and South Africa; metrication in Canada has displaced the imperial system in many areas.[80]. [58][59] On the other hand, the international prototype metre, manufactured from a platinum-iridium alloy rather than brass by a British firm, which in 1889 replaced the metre des archives as the standard for the metre, was found to be more stable than the standard yard. ≈ 0.96893897192 imp gal, ≈ 148.946839827 US fl oz [31] The bushel was not fully standardized and the Chicago Mercantile Exchange still (May 2013) uses different bushels for different commodities—a bushel of corn being 56 lb, a bushel of oats 38 lb and a bushel of soybeans 60 lb and a bushel of red winter wheat (both hard and soft) also 60 lb.

The imperial system of measurement and the US customary system of measurement are both derived from an earlier English system of measurement which in turn can be traced back to Ancient Roman units of measurement, and Carolingian and Saxon units of measure.. The subdivisions of the bushel were maintained. In all these systems, the fundamental unit is the pound (lb), and all other units are defined as fractions or multiples of it. It is nominally based upon the mass of a single virtual ideal seed of a cereal. [14] Many adopted the imperial system of units with local variations. The American system has two gallons: a wet and a dry one. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement but imperial units are still used in the United Kingdom, Canada and other countries formerly part of the British Empire. In England, all gallons are measured as one imperial gallon. Imperial vs US Measures Perhaps the most unusual, however, is the units of volume. The imperial system has a hundredweight, defined as eight Stone of 14 lbs each, or 112 lb (50.80234544 kg), whereas a US hundredweight is 100 lb (45.359237 kg). A barrel is 159 liters, or 42 US customary gallons. Both systems depend on the gravitational acceleration, and use the pound-force as the unit of force but use different approaches when applying Newton's laws of motion. It divides a pound into 12 ounces, an ounce into 8 drachms, and a drachm into 3 scruples of 20 grains each. Following the debacle over the different gallons that had been adopted by the United States and the United Kingdom thirty years earlier, one of the copies of the standard yard was offered to and accepted by the United States Government.[14]. avoirdupois pound. ≈ 0.15011874069 US gal, ≈ 1.03205674349 US dry pt Grain was measured with the Winchester measure with a gallon of approximately 268.8 cubic inches (one eighth of a Winchester bushel or 4.405 L). ≡ 4 US qt [lower-alpha 1] Originally defined as the volume of 10 pounds (4.54 kg) of distilled water (under certain conditions), [lower-alpha 2] then redefined by the Weights and Measures Act 1985 to be exactly 4.54609 L (277.4 cu in), the imperial gallon is close in size to the old ale gallon. they differ. Traditionally, both Britain and the US used three different weight systems: troy weight for precious metals, apothecaries' weight for medicines, and avoirdupois weight for almost all other purposes. Troy weight is a system of units of mass that originated in 15th-century England, and is primarily used in the precious metals industry. measure, which came from England and is relatively unchanged. Many Canadian brewers package beer in a 12-imperial-fluid-ounce bottles, which are 341 mL each. You could also do it yourself at any point in time. ≈ 151.536333333 US fl oz (food) The density, of a substance is its mass per unit volume. 160 imperial fluid ounces is equivalent to one imperial gallon, which is the approximate volume of 10 pounds or 160 avoirdupois ounces of water at 62 °F. Another difference arose when Britain abolished the troy pound (373.2417216 g) on January 1, 1879, leaving only the troy ounce (31.1034768 g) and its decimal subdivisions, whereas the troy pound (of 12 troy ounces) and pennyweight are still legal in the United States, although these are no longer widely used. Further, the term metric ton is used to denote a tonne (1000 kg, 2204.62262 lb), which is about 1.6% less than the long ton. In fact, the two systems are ≈ 0.87987699320 imp qt The British hundredweight is also called the long hundredweight and the Britsh ton is also called the long ton.
