[citation needed], Although kilolitres, megalitres, and gigalitres are commonly used for measuring water consumption, reservoir capacities and river flows, for larger volumes of fluids, such as annual consumption of tap water, lorry (truck) tanks, or swimming pools, the cubic metre is the general unit. Each case involves considering if the word is an official name or a proper noun. However, some authorities advise against some of them; for example, in the United States, NIST advocates using the millilitre or litre instead of the centilitre. NIST guides use American spelling.

In some computer typefaces, the two characters are barely distinguishable. Both "l" and "L" are internationally accepted. Additionally, the mass–volume relationship of water (as with any fluid) depends on temperature, pressure, purity and isotopic uniformity. Do not capitalize a unit of measure unless the abbreviation contains a capital letter. This entry refers not to a or an as abbreviations but to which of the two indefinite articles should precede a given abbreviation.

The plural forms are liters or litres, the accepted abbreviation is L, capitalized … This abbreviation is usually found on package labeling, in food preparation measurements, and to indicate a specific amount of liquid. One litre of water has a mass of almost exactly one kilogram when measured at its maximal density, which occurs at about 4 °C. [citation needed] The United States National Institute of Standards and Technology now recommends the use of the uppercase letter L,[9] a practice that is also widely followed in Canada and Australia. 1000 microliters = 1 milliliter 1,000,000 microliters = 1 liter (1000 milliliters = 1 liter) The prefix "micro" means one millionth (10-6) The prefix "milli" means one thousandth (10-3) Therefore there are 1,000,000 microliters in a liter and 1000 milliliters in a liter. In Spanish, that isn’t always the case. The L is capitalized because it is the proper form of the abbreviation for LITER. A litre is equal in volume to the millistere, an obsolete non-SI metric unit customarily used for dry measure. Other units may be found in the table below, where the more often used terms are in bold.

Primary units in the metric system are capitalized... such as M for Meter, L for Liter. SI unit of litre is abbreviated as 'L'. [a], One litre of liquid water has a mass of almost exactly one kilogram, because the kilogram was originally defined in 1795 as the mass of one cubic decimetre of water at the temperature of melting ice (0 °C). A cubic decimeter is a cube that has a special name, the liter (L): 1 dm 3 = 1 L A cubic decimeter contains 1000 cubic centimeters: 1 dm 3 - 1000 cm 3 A cubic centimeter equals a milliliter: 1 cm 3 - 1 mL. The word liter is derived from the French word litron, which is an archaic measurement for grain. a cubic metre, which is the SI unit for volume) is exactly 1000 L. From 1901 to 1964, the litre was defined as the volume of one kilogram of pure water at maximum density (+4 °C) and standard pressure. The Newton (after Isaac Newton) for measuring units of force The Watt (after James Watt) for measuring units of power, joules per second. There is only one common abbreviations of liter: “L”. Because volume changes with temperature and pressure, and pressure uses units of mass, the definition of a kilogram was changed. At standard pressure, one litre of water has a mass of 0.999975 kg at 4 °C, and 0.997 kg at 25 °C. A cubic decimetre (or litre) occupies a volume of 10 cm × 10 cm × 10 cm (see figure) and is thus equal to one-thousandth of a cubic metre. [4] In English, they’re often capitalized. The Metric Conversion Act of 1985 gives the, Isotopic composition and temperature per London South Bank University’s.
