A gallon is a measure of volume of approximately four litres. Historically it has had many different definitions, but there are three definitions in current use. These are the U.S. liquid gallon (≈ 3.8 L) and the lesser used U.S. dry gallon (≈ 4.4 L) which are in use in the United States, and the Imperial (UK) gallon (≈ 4.5 L) which is in unofficial use within the United Kingdom and Ireland and is in semi-official use within Canada. The gallon, be it the Imperial or U.S.
A hogshead 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 units or U.S. customary units, primarily applied to alcoholic beverages such as wine, ale, or cider. A tobacco hogshead was used in American colonial times to transport and store tobacco. It was a very large wooden barrel.
Lambda (uppercase Λ, lowercase λ; (λάβδα) in classical times. In; the letter itself is pronounced [l] as with Latin L. In early Greek alphabets, the shape and orientation of lambda varied. Most variants consisted of two straight strokes, one longer than the other, connected at their ends. The angle might be in the upper left, lower left ("Western" alphabets), or top ("Eastern" alphabets). Other variants had a vertical line with a horizontal or sloped stroke running to the right.
The litre (or liter - see spelling differences) is a unit of volume. There are two official symbols: the Latin letter L in lower and upper case (l and L). The lower case L is also often written as a cursive ℓ, though this symbol has no official approval by any international bureau. Although the litre is not an SI unit, it is accepted for use with the SI, and has appeared in several versions of the metric system. The official SI unit of volume is the cubic metre (m), equivalent to 1,000 litres.
In the United Kingdom, the ton is a unit of measure which, when it ceased to be legal for trade in 1985, was defined in British legislation as being a weight or mass [sic] equal to 2,240 pounds (1,016 kg). In the United States and Canada, however, a ton is defined to be 2,000 pounds (907 kg).
A teaspoon, an item of cutlery (in American English, also called flatware), is a small spoon, commonly part of a silverware (usually silver plated, German silver or now, stainless steel) place setting, suitable for stirring and sipping the contents of a cup of tea or coffee. Utilitarian versions are used for measuring. Teaspoons with longer handles, such as iced tea spoons, are commonly used also for ice cream deserts or floats.
A tablespoon is a type of large spoon usually used for serving. A tablespoonful, an amount approximately equal to the capacity of one tablespoon, is commonly used as a measure of volume in cooking. It is abbreviated in English as T, tb, tbs, tbsp, tblsp, or tblspn. Only the tbs and tbsp abbreviations are currently formally recognized, although the tblsp abbreviation is also commonly used informally. In most countries one level tablespoon is defined as 15 ml. In Australia it is defined as 20 ml.
A cubic centimetre (or cubic centimeter in US English) (symbol cm — the abbreviation cc, though widely used, is deprecated) is a commonly used unit of volume extending the derived SI-unit cubic metre, and corresponds to the volume of a cube measuring 1 cm × 1 cm × 1 cm. One cubic centimetre corresponds to a volume of ⁄1,000,000 of a cubic metre, or ⁄1000 of a litre, or one millilitre; thus, 1 cm ≡ 1 mL.
A peck is an imperial and U.S. customary unit of dry volume, equivalent in each of these systems to 2 gallons, 8 dry quarts, or 16 dry pints. Two pecks make a kenning (obsolete), and four pecks make a bushel. In Scotland, the peck was used as a dry measure until the introduction of imperial units as a result of the Weights and Measures Act of 1824.
A cubic inch is a non-SI unit of volume, equal to the volume of a cube with sides of one inch. Cubic inches are still sometimes used as a unit of measurement (in engineering contexts, not household contexts) in the United States and Canada, although SI is continuing to gradually displace non-SI usage.
The pint is an English unit of volume or capacity in the imperial system and United States customary units. The imperial version is 20 imperial fluid ounces and is equivalent to about 568 ml, while the U.S. version is 16 U.S. fluid ounces and is equivalent to about 473 ml. Pints are commonly abbreviated as either “p” or “pt”.
The quart is an imperial and US customary unit of volume equal to a quarter of a gallon, two pints, or four cups. Since gallons of various sizes have historically been in use, quarts of various sizes have also existed; see gallon for further discussion. Three of these quarts remain in current use, all approximately equal to one litre.
The board-foot is a specialized unit of measure for the volume of lumber in the United States and Canada. It is the volume of a one foot length of a board one foot wide and one inch thick. Board-foot can be abbreviated FBM (for "foot, board measure"), BDFT, or BF. Thousand board-feet can be abbreviated as MFBM or MBFT. In Australia and New Zealand the term super foot or superficial foot was used to mean the same.
The minim (abbreviated min or ♏) is a unit of volume in both the imperial and US customary systems of measurement. Specifically it is ⁄60 of a fluidram or ⁄480 of a fluid ounce. In contrast with apothecaries' weight, apothecaries' measure is a system both recent and short-lived. It seems to have arisen with the United Kingdom's defining of the new imperial gallon in 1824, and is fully described at least as early as 1878 in the Weights and Measures Act.
The stère is a measurement unit for volume of wood and equals one cubic metre. The name originally comes from the Greek stereos, meaning solid. It was created in France in 1793 as a metric equivalent to the cord, for measuring large quantities of firewood. The stère stands for cut up wood with spaces within the wood, while the cubic meter is used for uncut wood.
A fluid ounce (abbreviated fl oz, fl. oz. or oz. fl. ) is a unit of volume equal to about 29.57 ml, in the US. It is used in both the imperial and the US customary systems, and it is sometimes referred to simply as an ounce in cases where no confusion with the unit of weight (also called an ounce) is likely to occur.
The koku is a Japanese unit of volume, equal to ten cubic shaku. In this definition, 3.5937 koku equal one cubic metre, i.e. 1 koku is approximately 278.3 litres. The koku was originally defined as a quantity of rice, historically defined as enough rice to feed one person for one year (one masu is enough rice to feed a person for one day). A koku of rice weighs about 150 kilograms (23.6 stone or 330 pounds).
The oka, okka, or oke was an Ottoman measure of mass, equal to 400 dirhems. Its value varied, but it was standardized in the late empire as 1.2829 kilograms. 'Oka' is the most usual spelling today; 'oke' was the usual contemporary English spelling; 'okka' is the modern Turkish spelling, and is usually used in academic work about the Ottoman Empire. In Turkey, the traditional unit is now called the eski okka 'old oka' or kara okka 'black okka'; the yeni okka 'new okka' is the kilogram.
A bushel is an imperial and U.S. customary unit of dry volume, equivalent in each of these systems to 4 pecks or 8 gallons. It is used for volumes of dry commodities (not liquids), most often in agriculture. It is abbreviated as bsh. or bu. The name derives from the 14th century buschel or busschel, a box.
The femtolitre (US femtoliter) is the metric unit of volume equal to 10 litre, or one quindecillionth (European) or one quadrillionth (American) litre. It is abbreviated fL or fl. One femtolitre is the same as 1 μm.
The dram (archaic spelling drachm; apothecary symbol ℨ) was historically both a coin and a weight. Currently it is both a small mass in the Apothecaries' system of weights and a small unit of volume. This unit is called more correctly fluid dram or in contraction also fluidram.
A Firkin is an old English unit of volume. The name is derived from the Middle Dutch word vierdekijn, which means fourth, i.e. a quarter of a full-size barrel. Nor need you mind the serial ordeal Of being watched from forty cellar holes As if by eye pairs out of forty firkins. — Robert Frost, "Directive" For beer and ale a firkin is equal to nine imperial gallons, seventy-two pints, or a quarter of a barrel.
