Litres are most commonly used for items (such as fluids and solids that can be poured) which are measured by the capacity or size of their container, whereas cubic metres (and derived units) are most commonly used for items measured either by their dimensions or their displacements. The litre is often also used in some calculated measurements, such as density (kg/L), allowing an easy comparison with the density of water. It is now known that the density of water also depends on the isotopic ratios of the oxygen and hydrogen atoms in a particular sample. Modern measurements of Vienna Standard Mean Ocean Water, which is pure distilled water with an isotopic composition representative of the average of the world's oceans, show that it has a density of 0.999 975 ±0.000 001kg/L at its point of maximum density (3.984°C) under one standard atmosphere (101.325 kPa) of pressure.

Guarantee Terms From 1901 to 1964, the litre was defined as the volume of one kilogram of pure water at maximum density (+3.98°C) [ citation needed] and standard pressure. The kilogram was in turn specified as the mass of the International Prototype of the Kilogram (a specific platinum/iridium cylinder) and was intended to be of the same mass as the 1litre of water referred to above. It was subsequently discovered that the cylinder was around 28 parts per million too large and thus, during this time, a litre was about 1.000 028dm 3. Additionally, the mass–volume relationship of water (as with any fluid) depends on temperature, pressure, purity and isotopic uniformity. In 1964, the definition relating the litre to mass was superseded by the current one. Although the litre is not an SI unit, it is accepted by the CGPM (the standards body that defines the SI) for use with the SI. CGPM defines the litre and its acceptable symbols.

The microlitre (μL) has been known in the past as the lambda (λ), but this usage is now discouraged. [15] In the medical field the microlitre is sometimes abbreviated as mcL on test results.

One litre of water has a mass of almost exactly one kilogram when measured at its maximal density, which occurs at about 4°C. It follows, therefore, that 1000th of a litre, known as one millilitre (1 mL), of water has a mass of about 1g; 1000litres of water has a mass of about 1000kg (1 tonne or megagram). This relationship holds because the gram was originally defined as the mass of 1mL of water; however, this definition was abandoned in 1799 because the density of water changes with temperature and, very slightly, with pressure.

A litre is equal in volume to the millistere, an obsolete non-SI metric unit formerly customarily used for dry measure.

a b Bureau International des Poids et Mesures, 2006, p. 124. ("Days" and "hours" are examples of other non-SI units that SI accepts.) 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 [2]—via Late Medieval Latin, and which equalled approximately 0.831litres. The litre was also used in several subsequent versions of the metric system and is accepted for use with the SI, [3] although not an SI unit—the SI unit of volume is the cubic metre (m 3). The spelling used by the International Bureau of Weights and Measures is "litre", [3] a spelling which is shared by most English-speaking countries. The spelling "liter" is predominantly used in American English. [a] The International System of Units (SI)" (PDF). 2006. p.124. Archived from the original (PDF) on 14 August 2017 .
