U.S. customary units is the system of units of measurement used to measure things in the United States.The system of Imperial units is similar and in some parts identical.. Furthermore, Canada aligned her ton with US measures by cataloguing the ton of 2000 lb as being legal for trade, but kept the imperial gallon.[28]. They were a precursor to both the imperial system of units (first defined in 1824, to take effect in 1826) and United States customary units which evolved from English Units from 1776 onwards. The Imperial System is also called The British Imperial because it came from the British Empire that ruled many parts of the world from the 16th to the 19th century. [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. Broch, director of the BIPM replied that he was not authorised to perform any such calibrations for non-member states. Prior to metrication, the units of measure used in the Ireland were the same as those used in the United Kingdom while those used in the British Commonwealth and in South Africa were in most cases a subset of those used in the United Kingdom with, in certain cases, local differences. During the twentieth century the principal change in the customary system of weights and measures was an agreement between NIST and the corresponding bodies in Australia, Canada, New Zealand, South Africa and the United Kingdom, signed in 1960, that redefined the yard and the pound in terms of the metre and the kilogram respectively. [11]:90–91 The Acts of Union 1800 which united Ireland with Great Britain had less of an effect on weights and measures—Irish weights and measures having been based on the English foot and pound avoirdupois since 1351, though the Irish acre and mile were based on a perch of 7 yards, not ​5 1⁄2 yards as in England. The bushel, which like the gallon, had definitions reflecting the various gallons, was defined as 8 imperial gallons. Generell gilt, dass die Verbrauchsangaben weltweit nach unterschiedlichen Standards ermittelt werden und somit eine Umrechnung nur eine begrenzte Aussagekraft hat (siehe auch Kraftstoffverbrauch). Units of weight in both the imperial and US customary system always used the same standard, though differences in multiples of the avoirdupois pound developed in the nineteenth century. [1], The earliest records of English units of measure involve the weight (and therefore the value) of Saxon coins. Dabei wären sie in den Siebzigerjahren fast auf den Meter gekommen. As of 24 April 2012, troy ounces are still legal for the sale of precious metals. [49][50][Note 4] Two years later James Thomson, older brother of William Thomson, introduced the term poundal as a coherent unit of force in the Foot–pound–second system (FPS) of measurement. [74], The definitions of potential difference (volt), electric current (ampere), electrical resistance (ohm) were defined in terms of metric units, international agreement having been reached at a series of IEC Congress in Chicago between 1881 and 1906 when the electrical industry was in its infancy. An Act of Parliament in 1824 created it from traditional English units. [53] On the other hand, the EE system uses a different approach and introduces the acceleration due to gravity (g) into its equations. In 1832, in the absence of any direction by Congress, the United States Treasury chose the second smallest gallon, the "Queen Anne gallon" of 231 cubic inches (3.785 litres), to be the official gallon in the United States for fiscal purposes. Such units could, in theory, be replaced by general units of the same dimension, for example the barrel (42 US gallons, 34.97 imperial gallons or 159.0 litres) used in the oil industry has the dimension of volume and could be replaced by the gallon, cubic metre or litre. I must admit I was not disappointed at all. Selten wird dort auch die Einheit Kilometer pro Liter verwendet, insbesondere in den NWT. [11]:85–88, The British Weights and Measures Act of 1824 repealed all existing British weights and measures legislation, some dating back to the 1300s, and redefined existing units of measure. [75] At that time the metric system had become established in continental Europe while in the United Kingdom metrication was an active issue. The metric system was designed by over-rationalist, naive French people who also thought it would be a neat idea to divide time into tens. In Kanada sind sowohl l⁄100 km als auch mpg (UK) möglich. The Imperial system standardized measurements for units like pound and foot that had different meanings in different places. The current status of imperial and US customary units, as summarised by NIST, is that "the SI metric system is now the official system of units in the United Kingdom, while the customary units are still predominantly used in the United States". The Imperial system, sometimes referred to as the English system of units is an old system of measurements that was used throughout human history, with evidence of its use in ancient Greece, ancient Rome, the Middle ages, and more. Anders als bei vielen anderen Einheitensystemen mit unhandlich großen oder kleinen Angaben werden im metrischen Einheitensystem alle Werte strikt als dezimale Vielfache oder dezimale Bruchteile angegeben. (See § Metric equivalents). In this context, the plural is "stone", not "stones". Die Einheit wird in Arbeitsschutzvorgaben für die Ausleuchtung von Arbeitsplätzen, Wegen und Räumen genutzt, wie auch für die Beleuchtung von Straßen, Plätzen und öffentlichen Räumen. Newton's second law in these systems becomes: AE is ignored in many engineering courses and textbooks[55][56] while some, such as Darby only uses EE (alongside SI), having described the BG and EE systems as "archaic". The imperial system of units was developed and used in the United Kingdom and its empire beginning in 1826. In addition, the definitions of both the yard and the pound in terms of the artifacts held by the British Government was reaffirmed giving both the yard and the pound two different definitions. Some units of measure such as the horsepower or the British thermal unit (BTU) have special names but by and large unit names are generated from their constituent components – for example, pounds per square inch. The British thermal unit (Btu) is defined as the heat needed to raise the temperature of one pound of water by one degree Fahrenheit. In den USA wird auf Konsumenten-, Produktions- und Handelsebene bis zur Ingenieursebene die Beleuchtungsstärke nach dem United States customary units-System mit der Einheit Foot-candle (Lumen pro Quadratfuß) angegeben. [64], This agreement was ratified by the United Kingdom in 1963 while Canada pre-empted the decision by adopting these values in 1951, nine years ahead of the full international agreement. 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]. Edward the Elder increased the weight of the English penny to 26 grains (1.685 g), thereby aligning it with the penny of Charlemagne. Finally, because the US market for rebar operates on the imperial system as opposed to the metric system in Canada, to get access to this market, the Canadian producers would need to invest in new rolls to make the imperial sizes. [77], The situation is however not as clear-cut as this. [20][21][Note 2] Since 1 January 2000 it has been unlawful to use imperial units for weights and measures in retail trade in the United Kingdom except as supplementary units or for the sale of draught beer and cider by the pint or milk that is sold in returnable containers. [39] Inactivity by Congress and the lack of uniformity of weights and measures which were crippling US economic growth in the nineteenth century led to the National Bureau of Standards to call a meeting of states in 1905 which resulted in the setting up of the National Conference on Weights and Measures (NCWM). At the same time, the stone, when used to weigh wool, was formalized as being 14 pounds. The act also reaffirmed the use of the brass standard yard and platinum standard pound as the standards for use in the United Kingdom, reaffirmed the use of apothecaries measures in the pharmaceutical industry, reaffirmed the 1824 definition of the gallon, removed the Troy pound from the list of legal units of measure, added the fathom to the list of legal units and fixed the ratio of metric to imperial units at one metre being equal to 39.3708 inches and one kilogram being equal to 15432.3487 grains (1 lb = 0.453592654 kg). Da die Gallone in der Variante U.S. For many years no action was taken at the federal level to ensure harmony in units of measure – the units acquired by the early colonists appeared to serve their purpose. The United Kingdom overhauled its system of measurement in 1826, when it introduced the imperial system of units. Both systems used the three different scales – the avoirdupois system for general use, the troy system for precious metals and the apothecaries system in the pharmacy industry.

[1] Apart from the ell (45 inches or 114.3 cm, which continued to be used in the cloth trade) and the chain (introduced by Edmund Gunter in 1620, and used in land surveying), these units formed the basis of the units of length of the English system of measurement. Es bleibt ihnen nichts anderes übrig, als sich nach und nach an das überlegene metrische System zu gewöhnen und seine kleineren Einheiten zu übernehmen. The imperial system has a hundredweight, defined as eight Stone of 14 lbs each, or 112 lb … [62] In the United Kingdom fresh comparisons of the imperial and metric standards of length and mass were made and were used in the Weights and Measures Act 1897 to redefine the yard and pound in terms of the metre and kilogram respectively. This page was last edited on 9 January 2021, at 21:30. Following a report published in 1841 by a commission new standard yard and pound were manufactured using the best available secondary sources. Mit „Metrisch“ und „Imperial“ ist das Maßsystem gemeint. Imperial units, also called British Imperial System, units of measurement of the British Imperial System, the traditional system of weights and measures used officially in Great Britain from 1824 until the adoption of the metric system beginning in 1965. The horsepower is now defined as the power required to raise 550 pounds of water a distance of one foot in one second. Es gibt noch. [2]:123, Under the Act of Union of 1707, Scotland, which had developed its own system of weights and measures independently of England, abandoned them in favour of English weights and measures. In the BG system, force, rather than mass has a base unit while the slug is a derived unit of inertia (rather than mass). Energy required to raise the temperature of 1 lb liquid water by 1 °F (−17 °C). [2]:91–94, During the Tudor period, numerous reforms were made to English weights and measures. [19] The differences between the British and the US yard and pound was of the order of a few parts per million. [11]:116, By the early nineteenth century many commodities had their own set of units, the units of measure for the wool and cloth industries had units of measure specific to those commodities, albeit derived on the pound avoirdupois or the foot while wine and beer used units with the same names but different sizes – the wine gallon being 231 cubic inches and the beer or ale gallon being 282 cubic inches. [Note 10], In addition to those catalogued above, there are literally hundreds of other units of measure in both the imperial and the US customary system of measurement – many are specific to a particular industry of application.
