One-litre beer mugs (German: Maßkrüge) at the 2006 Oktoberfest in Germany. The litre (Commonwealth spelling) or liter (American spelling) (SI symbols L and l, [1] other symbol used: ℓ) is a metric unit of volume. It is equal to 1 cubic decimetre (dm 3), 1000 cubic centimetres (cm 3) or 0.001 cubic metres (m 3).
The system can be traced back to the measuring systems of the Hindus [18]: B-9 and the ancient Egyptians, who subdivided the hekat (about 4.8 litres) into parts of 1 ⁄ 2, 1 ⁄ 4, 1 ⁄ 8, 1 ⁄ 16, 1 ⁄ 32, and 1 ⁄ 64 (1 ro, or mouthful, or about 14.5 ml), [19] and the hin similarly down to 1 ⁄ 32 (1 ro) using hieratic notation, [20] as ...
In India, the seer was a traditional unit used mostly in Northern India including Hindi speaking region, Telangana in South. Officially, seer was defined by the Standards of Weights and Measures Act (No. 89 of 1956, amended in 1960 and 1964) as being exactly equal to 1.25 kilograms (2.8 lb).
C-19 [9] One gram is thus approximately equivalent to 15.432 36 grains. [6]: C-13 The unit formerly used by jewellers to measure pearls, diamonds, and other precious stones, called the jeweller's grain or pearl grain, is equal to 1 ⁄ 4 carat (50 mg; 0.77 gr). [5] The grain was also the name of a traditional French unit equal to 53.115 mg. [5]
The gram (originally gramme; [1] SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one thousandth of a kilogram.. Originally defined in 1795 as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre [1 cm 3], and at the temperature of melting ice", [2] the defining temperature (≈0 °C) was later changed to 4 °C ...
Convenient "pau" units of both 200 grams and 250 grams are in current use in retail sales in different parts of the country. In Pakistan, the pao was slightly heavier, at 233.3 grams. [6] As to Afghanistan, it was reported in 1950 that 1 pao ≈ 1 lb (450 grams) in Kabul, with four paos to one charak and sixteen paos to a seer. [7]
One GGE of natural gas is 126.67 cubic feet (3.587 m 3) at standard conditions. This volume of natural gas has the same energy content as one US gallon of gasoline (based on lower heating values : 900 BTU/cu ft (9.3 kWh/m 3 ) of natural gas and 114,000 BTU/US gal (8.8 kWh/L) for gasoline).
The ideal gas equation can be rearranged to give an expression for the molar volume of an ideal gas: = = Hence, for a given temperature and pressure, the molar volume is the same for all ideal gases and is based on the gas constant: R = 8.314 462 618 153 24 m 3 ⋅Pa⋅K −1 ⋅mol −1, or about 8.205 736 608 095 96 × 10 −5 m 3 ⋅atm⋅K ...
