Tun (unit)
The tun ( ang, tunne, la, tunellus, ) is an English unit of ''liquid volume'' (not weight), used for measuring wine, oil or honey. Typically a large vat or vessel, most often holding 252 wine gallons, but occasionally other sizes (e.g. 256, 240 and 208 gallons) were also used. The modern tun is about 954 litres. The word ''tun'' is etymologically related to the word ''ton'' for the unit of mass, the mass of a tun of wine being approximately one long ton, which is . History Originally, the tun was defined as 256 wine gallons; this is the basis for the name of the quarter of 64  corn gallons. At some time before the 15th century, it was reduced to 252 gallons, so as to be evenly divisible by other small integers, including seven.252 =  In one Early Modern English example from 1507, a tun is defined as 240 gallons. With the adoption of the Queen Anne wine gallon of 231 cubic inches in 1706 the tun approximated the volume of a cylinder with both dia ...

English Wine Cask Units
Capacities of wine casks were formerly measured and standardised according to a specific system of English units. The various units were historically defined in terms of the wine gallon so varied according to the definition of the gallon until the adoption of the Queen Anne wine gallon in 1707. In the United Kingdom and its colonies the units were redefined with the introduction of the imperial system whilst the Queen Anne wine gallon was adopted as the standard US liquid gallon. The major wine producing countries use barrels extensively and have developed standards at variance with the traditional English volumes that are commonly used in the wine and wine cooperage industries. Examples include a hogshead of , a barrique of (Bordeaux), a barrel of (Australia), a barrel of (Burgundy) and a puncheon of . Casks Tun The tun ( ang, tunne, la, tunellus, Middle Latin: ') is an English unit of ''liquid volume'' (not weight), used for measuring wine, oil or honey. It is typical ...

Gallon
The gallon is a unit of volume in imperial units and United States customary units. Three different versions are in current use: *the imperial gallon (imp gal), defined as , which is or was used in the United Kingdom, Ireland, Canada, Australia, New Zealand, and some Caribbean countries; *the US gallon (US gal), defined as , (231 cubic inches) which is used in the US and some Latin American and Caribbean countries; and *the US dry gallon ("usdrygal"), defined as US bushel (exactly ). There are two pints in a quart and four quarts in a gallon. Different sizes of pints account for the different sizes of the imperial and US gallons. The IEEE standard symbol for both US (liquid) and imperial gallon is gal, not to be confused with the gal (symbol: Gal), a CGS unit of acceleration. Definitions The gallon currently has one definition in the imperial system, and two definitions (liquid and dry) in the US customary system. Historically, there were many definitions and redefiniti ...

Cubic Metre
The cubic metre (in Commonwealth English and international spelling as used by the International Bureau of Weights and Measures) or cubic meter (in American English) is the unit of volume in the International System of Units (SI). Its symbol is m3. Bureau International de Poids et Mesures.Derived units expressed in terms of base units". 2014. Accessed 7 August 2014. It is the volume of a cube with edges one metre in length. An alternative name, which allowed a different usage with metric prefixes, was the stère, still sometimes used for dry measure (for instance, in reference to wood). Another alternative name, no longer widely used, was the kilolitre. Conversions : A cubic metre of pure water at the temperature of maximum density (3.98 °C) and standard atmospheric pressure (101.325 kPa) has a mass of , or one tonne. At 0 °C, the freezing point of water, a cubic metre of water has slightly less mass, 999.972 kilograms. A cubic metre is sometimes abbreviated ...

Litre
The litre (international spelling) or liter (American English spelling) (SI symbols L and l, other symbol used: ℓ) is a metric unit of volume. It is equal to 1 cubic decimetre (dm3), 1000 cubic centimetres (cm3) or 0.001 cubic metre (m3). A cubic decimetre (or litre) occupies a volume of (see figure) and is thus equal to one-thousandth of a cubic metre. The original French metric system used the litre as a base unit. The word ''litre'' is derived from an older French unit, the '' litron'', whose name came from Byzantine Greek—where it was a unit of weight, not volume—via Late Medieval Latin, and which equalled approximately 0.831 litres. The litre was also used in several subsequent versions of the metric system and is accepted for use with the SI,Bureau International des Poids et M ...

Pint
The pint (, ; symbol pt, sometimes abbreviated as ''p'') is a unit of volume or capacity in both the imperial unit, imperial and United States customary units, United States customary measurement systems. In both of those systems it is traditionally one eighth of a gallon. The British imperial pint is about 20% larger than the American pint because Comparison of the imperial and US customary measurement systems, the two systems are defined differently. Almost all other countries have standardized on the metric system, so although some of them still also have traditional units called pints (such as for beverages), the volume varies by regional custom. The imperial pint (≈) is used in the United Kingdom and Ireland and to a limited extent in Commonwealth of Nations, Commonwealth nations. In the United States, two kinds of pint are used: a liquid pint (≈) and a less-common dry pint (≈). Other Dominion , former British colonies, such as Canada, Australia, South Africa and New Z ...

Barrel (unit)
A barrel is one of several units of volume applied in various contexts; there are dry barrels, fluid barrels (such as the U.K. beer barrel and U.S. beer barrel), oil barrels, and so forth. For historical reasons the volumes of some barrel units are roughly double the volumes of others; volumes in common use range approximately from . In many connections the term is used almost interchangeably with ''barrel''. Since medieval times the term as a unit of measure has had various meanings throughout Europe, ranging from about 100 litres to about 1,000 litres. The name was derived in medieval times from the French , of unknown origin, but still in use, both in French and as derivations in many other languages such as Italian, Polish, and Spanish. In most countries such usage is obsolescent, increasingly superseded by SI units. As a result, the meaning of corresponding words and related concepts (vat, cask, keg etc.) in other languages often refers to a physical container ...

Tierce (unit)
The tierce (also ''terse'') is both an archaic volume unit of measure of goods and the name of the cask of that size. The most common definitions are either one-third of a pipe or forty-two gallons. In the petroleum industry - a barrel of oil is defined as 42 US gallons. Use The casks were roughly 20.5 inches across and were built to hold either liquids (wet cooperage) or dry goods (dry cooperage). Contents ranged from sugar to rum to salted beef and fish. History The Oxford English Dictionary lists the first use of the term in this sense as occurring in 1531. In 1630, Ben Jonson, then the Poet Laureate of England, petitioned that the salary of the position be raised. His wish was granted, and in addition he and his successors received a tierce of wine from the Canary Islands, a tradition that continued until Henry James Pye became Laureate in 1790. As opposed to several other units of measure such as the pipe, cark and frail, the definition of the tierce remained stable with s ...

Hogshead
A hogshead (abbreviated "hhd", plural "hhds") is a large cask of liquid (or, less often, of a food commodity). More specifically, it refers to a specified volume, measured in either imperial or US customary measures, primarily applied to alcoholic beverages, such as wine, ale, or cider. Etymology English philologist Walter William Skeat (1835–1912) noted the origin is to be found in the name for a cask or liquid measure appearing in various forms in Germanic languages, in Dutch ''oxhooft'' (modern ''okshoofd''), Danish ''oxehoved'', Old Swedish ''oxhuvud'', etc. The ''Encyclopædia Britannica'' of 1911 conjectured that the word should therefore be "oxhead", "hogshead" being a mere corruption. Varieties and standardisation A tobacco hogshead was used in British and American colonial times to transport and store tobacco. It was a very large wooden barrel. A standardized hogshead measured long and in diameter at the head (at least , depending on the width in the middle). Fu ...

Butt (unit)
The butt is an obsolete English measure of liquid volume equalling two hogsheads, being between by various definitions. Equivalents A butt approximately equated to for ale or for wine (also known as a ''pipe''), although the ''Oxford English Dictionary'' notes that "these standards were not always precisely adhered to". The butt is one in a series of English wine cask units, being half of a ''tun TUN or tun may refer to: Biology * Tun shells, large sea snails of the family ''Tonnidae'' * Tun, a tardigrade in its cryptobiotic state * Tun or Toon, common name for trees of the genus '' Toona'' Places * Tun, Sweden, a locality in Västra G ...''.

United States Customary Units
United States customary units form a system of measurement units commonly used in the United States and U.S. territories since being standardized and adopted in 1832. The United States customary system (USCS or USC) developed from English units which were in use in the British Empire before the U.S. became an independent country. The United Kingdom's system of measures was overhauled in 1824 to create the imperial system, which was officially adopted in 1826, changing the definitions of some of its units. Consequently, while many U.S. units are essentially similar to their imperial counterparts, there are significant differences between the systems. The majority of U.S. customary units were redefined in terms of the meter and kilogram with the Mendenhall Order of 1893 and, in practice, for many years before. T.C. Mendenhall, Superintendent of Standard Weights and MeasuresOrder of April 5, 1893, published as Appendix 6 to the Report for 1893 of the United States Coast and G ...

International Yard And Pound
The international yard and pound are two units of measurement that were the subject of an agreement among representatives of six nations signed on 1 July 1959: the United States, United Kingdom, Canada, Australia, New Zealand, and South Africa. The agreement defined the yard as exactly and the avoirdupois pound as exactly . History In October 1834, the United Kingdom Houses of Parliament were destroyed in a fire. Among the items lost were the objects that defined the imperial standards of length and mass. New prototypes were subsequently created to replace the items lost in the fire, among them a new "yardstick" ruler in 1855, and with it a new formal definition of the yard. Two copies of the ruler were subsequently presented to the United States, which in turn adopted the measure for the United States national standard yard. In 1866, the U.S. Congress passed a law that allowed, but did not require, the use of the metric system in trade and commerce. Included in the law was a ...
