The inch is a unit of length in the British Imperial and the United States customary systems of measurement. It is equal to 1/36 yard or 1/12 of a foot. Derived from the Roman uncia ("twelfth"), the word inch is also sometimes used to translate similar units in other measurement systems, usually understood as deriving from the width of the human thumb.
The imperial system of units, imperial system or imperial units 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.
The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of length; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised between the Commonwealth of Nations and the United States by an international agreement in 1959, when it was formally redefined with respect to SI units as exactly 1,609.344 metres.
The pound or pound-mass is a unit of mass used in both the British imperial and United States customary systems of measurement. Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly 0.45359237 kilograms, and which is divided into 16 avoirdupois ounces. The international standard symbol for the avoirdupois pound is lb; an alternative symbol is lbm, #, and ℔ or ″̶.
The yard is an English unit of length in both the British imperial and US customary systems of measurement equalling 3 feet or 36 inches. Since 1959 it has been by international agreement standardized as exactly 0.9144 meter. A distance of 1,760 yards is equal to 1 mile.
The foot is a unit of length in the British imperial and United States customary systems of measurement. The prime symbol, ′, is commonly used to represent the foot. In both customary and imperial units, one foot comprises 12 inches, and one yard comprises three feet. Since an international agreement in 1959, the foot is defined as equal to exactly 0.3048 meters.
A bushel is an imperial and US customary unit of volume based upon an earlier measure of dry capacity. The old bushel is equal to 2 kennings (obsolete), 4 pecks, or 8 dry gallons, and was used mostly for agricultural products, such as wheat. In modern usage, the volume is nominal, with bushels denoting a mass defined differently for each commodity.
The stone or stone weight is an English and British imperial unit of mass equal to 14 avoirdupois pounds (6.35 kg). The stone continues in customary use in the United Kingdom and Ireland for body weight.
The carucate or carrucate was a medieval unit of land area approximating the land a plough team of eight oxen could till in a single annual season. It was known by different regional names and fell under different forms of tax assessment.
An ell is a northwestern European unit of measurement, originally understood as a cubit. The word literally means "arm", and survives in the modern English word "elbow" (arm-bend). Later usage through the 19th century refers to several longer units, some of which are thought to derive from a "double ell".
English units were the units of measurement used in England up to 1826, which evolved as a combination of the Anglo-Saxon and Roman systems of units. Various standards have applied to English units at different times, in different places, and for different applications.
The davoch, davach or daugh is an ancient Scottish land measurement. All of these terms are cognate with modern Scottish Gaelic dabhach. The word dabh or damh means an "ox", but dabhach can also refer to a "tub", so may indicate productivity. It was called the arachor in the Lennox.
An ounceland is a traditional Scottish land measurement. It was found in the West Highlands, and Hebrides. In Eastern Scotland, other measuring systems were used instead. It was equivalent to 20 pennylands or one eighth of a markland. Like those measurements, it is based on the rent paid, rather than the actual land area. It was also known as a "tirung", or a dabhach, which is a term of Pictish origin, also used in the east of Scotland too, but for a different measurement. The “ounceland” is thought to be of Norse origin, so it is possible that Norse (‘ounceland’) and native systems (dabhach) were conflated in the west.
An oxgang or bovate is an old land measurement formerly used in Scotland and England as early as the 16th century sometimes referred to as an oxgait. It averaged around 20 English acres, but was based on land fertility and cultivation, and so could be as low as 15.
A markland or merkland is an old Scottish unit of land measurement.
A Scottish or Scots acre was a land measurement used in Scotland. It was standardised in 1661. When the Weights and Measures Act of 1824 was implemented the English System was standardised into the Imperial System and Imperial acres were imposed throughout the United Kingdom, including in Scotland and indeed throughout the British Empire from that point on. However, since then the metric system has come to be used in Scotland, as in the rest of the United Kingdom..
A groatland, also known as a fourpenceland, fourpennyland or “Còta bàn” was a Scottish land measurement. It was so called, because the annual rent paid on it was a Scottish “groat” (coin).
Oxgangs is a suburb in the south-west of Edinburgh, Scotland. Surrounding districts include Caiystane, Dreghorn, Redford, Fairmilehead, Colinton and Swanston and Colinton Mains. The post code area for Oxgangs is EH13.
A fall or fa’ is a Scottish measurement of length. Other variants of the name include "faw", "faa" and "fa"; the spelling with an apologetic apostrophe is not favoured now. The measurement was mostly out of use by the 19th century, and English measurements were imposed in 1824 by an act of parliament.
The imperial and US customary measurement systems 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.
