litre(ˈliːtə(r)) (American) liter (ˈliːtə) nounliter→ 升zhCNliterliter,abbr. l, unit of volume in the metric systemmetric system,system of weights and measures planned in France and adopted there in 1799; it has since been adopted by most of the technologically developed countries of the world. .....

The liter is equal to 1.057 liquid quarts, 0.908 dry quarts, and 61.024 cubic inches. Literthe unit of volume and capacity in the metric system of measurement. It is designated by the letter l. According to a decision of the Third General Conference on Weights and Measures (1901) the liter was defined as the volume of 1 kg of pure water at normal atmospheric pressure (105 kilonewtons per sq m, or 760 mm of mercury) and the temperature of greatest water density (4°C); 1 l = 1.000028 cubic decimeters (dm3). The Twelfth General Conference on Weights and Measures (1964) abolished this definition and adopted 1 l = 1 dm3 (precisely). The term “liter” may now be used as a special name for “dm3” in cases that do not express the results of highly precise measurements. liter[lēd·ər]liter, litrelitre(US), literliterSI unitsSI is a coherent system. This means that units are always combined without conversion factors. The derived unit of velocity is the meter per second (m/s); the derived unit of volume is the cubic meter (m3). If you know that pressure is force per unit area, then you know that the SI unit of pressure (the pascal) is the unit of force divided by the unit of area and is therefore equal to 1 newton per square meter. The metric prefixes can be attached to any unit in order to make a unit of a more convenient size. The symbol for the prefix is attached to the symbol for the unit, e.g., nanometer (nm) = 10−9 m. The units of mass are specified in terms of the gram, e.g., microgram (μg) = 10−9 kg. Only one prefix is used with a unit; the use of units such as the millimicrometer is no longer acceptable. When a unit is raised to a power, the power applies to the prefix as well, e.g., a cubic millimeter (mm3) = 10−9 m3. When a prefix is used with a ratio unit, it should be in the numerator rather than in the denominator, e.g., kilometers/second (km/s) rather than meters/millisecond (m/ms). Only prefixes denoting powers of 103 are normally used. Hecto-, deka-, deci-, and centi- are usually attached only to the metric system units gram, meter, and liter. Owing to the force of tradition, one noncoherent unit, the liter, equal to 10−3 m3, or 1 dm3, is generally accepted for use with SI. The internationally accepted abbreviation for liter is the letter l; however, this can be confused with the numeral 1, especially in typescript. For this reason, the capital letter L is also used as a symbol for liter. The lower case letter is generally used with prefixes, e.g., dl, ml, fl. The symbols for all other SI units begin with a capital letter if the unit is named after a person and with a lower case letter otherwise. The name of a unit is never capitalized. li·ter (L, l),(lē'tĕr), Although the SI unit of volume is the cubic meter and, by extension, the cubic centimeter (1 cm3=0.000 001 m3), the liter and its submultiples are preferred to the cubic meter and its submultiples for the expression of volumes and substance or mass concentrations in clinical chemistry. For practical purposes 1 cubic decimeter (dm3) = 1 liter (L). It recommended that capital (L) be used as the abbreviation of liter because the lowercase l can easily be misread as the numeral 1.li·ter(L) (lē'těr)Synonym(s): litre. li·ter(L) (lē'těr)Synonym(s): litre.
