British Imperial System, traditional system of weights and measures used officially in Great Britain from 1824 until the adoption of the metric system beginning in 1965. The United States Customary System of weights and measures is derived from it. British Imperial units are now legally defined in metric terms.
The British Imperial System evolved from the thousands of Roman, Celtic, Anglo-Saxon, and customary local units employed in the Middle Ages. Traditional names such as pound, foot, and gallon were widely used, but the values so designated varied with time, place, trade, product specifications, and dozens of other requirements. Early royal standards established to enforce uniformity took the name Winchester, after the ancient capital of Britain, where the 10th-century Saxon king Edgar the Peaceable kept a royal bushel measure and quite possibly others. Fourteenth-century statutes recorded a yard (perhaps based originally on a rod or stick) of 3 feet, each foot containing 12 inches, each inch equaling the length of three barleycorns (employed merely as a learning device since the actual standard was the space between two marks on a yardbar). Units of capacity and weight were also specified. In the late 15th century, King Henry VII reaffirmed the customary Winchester standards for capacity and length and distributed royal standards (physical embodiments of the approved units) throughout the realm. This process was repeated about a century later in the reign of Queen Elizabeth I. In the 16th century the rod (5.5 yards, or 16.5 feet) was defined (once again as a learning device and not as a standard) as the length of the left feet of 16 men lined up heel to toe as they emerged from church. By the 17th century usage and statute had established the acre, rod, and furlong at their present values (4,840 square yards, 16.5 feet, and 660 feet, respectively), together with other historic units. The several trade poundsin common use were reduced to just two: the troy pound, primarily for precious metals, and the pound avoirdupois, for other goods sold by weight.
ESTABLISHMENT OF THE SYSTEM
The Weights and Measures Act of 1824 and the Act of 1878 established the British Imperial System on the basis of precise definitions of selected existing units. The 1824 act sanctioned a single imperial gallon to replace the wine, ale, and corn (wheat) gallons then in general use. The new gallon was defined as equal in volume to 10 pounds avoirdupois of distilled water weighed at 62 °F with the barometer at 30 inches, or 277.274 cubic inches (later corrected to 277.421 cubic inches). The two new basic standard units were the imperial standard yard and the troy pound, which was later restricted to weighing drugs, precious metals, and jewels. A 1963 act abolished such archaic measures as the rod and chaldron (a measure of coal equal to 36 bushels) and redefined the standard yard and pound as 0.9144 metres and 0.45359237 kg respectively. The gallon now equals the space occupied by 10 pounds of distilled water of density 0.998859 gram per millilitre weighed in air of density 0.001217 gram per millilitre against weights of density 8.136 grams per millilitre.
While the British were reforming their weights and measures in the 19th century, the Americans were just adopting units based on those discarded by the act of 1824. The standard U.S. gallon is based on the Queen Anne wine gallon of 231 cubic inches and is about 17 percent smaller than the British imperial gallon. The U.S. bushel of 2,150.42 cubic inches, derived from the Winchester bushel abandoned in Britain, is approximately 3 percent smaller than the British imperial bushel. In the British system, units of dry and liquid capacity are the same, while in the United States they differ; the liquid and dry pint in Britain both equal 0.568 cubic decimetre, while the U.S. liquid pint is 0.473 cubic decimetre, and the U.S. dry pint is 0.551 cubic decimetre. British and American units of linear measure and weight are essentially the same. Notable exceptions are the British stone of 14 pounds, which is not used in the United States, and a divergence in definition of the hundredweight (100 pounds in the United States, 112 in Britain) that yields two different tons, the short U.S. ton of 2,000 pounds and the long British ton of 2,240 pounds. In 1959 major English-speaking nations adopted common metric definitions of the inch (2.54 cm), the yard (0.9144 metres), and the pound (0.4536 kg).

Peterborough (i) is a cathedral city and unitary authority area in the East of England, with a population measured as 183,631 in 2011. Historically part of Northamptonshire, for ceremonial purposes it now falls within the county of Cambridgeshire. Situated 75 miles (121 km) north of London, the city stands on the River Nene which flows into the North Sea approximately 30 miles (48 km) to the north-east. The railway station is an important stop on the East Coast Main Line between London and Edinburgh. The unitary authority borders Northamptonshire and Rutland to the west, Lincolnshire to the north, and non-metropolitan Cambridgeshire to the south and east.
