the 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.
