In these countries, the symbol L is also used with prefixes, as in mL and μL, instead of the traditional ml and μl used in Europe. Thus, measures such as kg, km and kph are nearly always in lower-case. A good number of scientific papers use mL as well as Joint Commission on Accreditation of Healthcare Organizations. In 1901, at the 3rd CGPM conference, the litre was redefined as the space occupied by 1 kg of pure water at the temperature of its maximum density (3.98 °C) under a pressure of 1 atm. This abbreviation is usually found on package labeling, in food preparation measurements, and to indicate a specific amount of liquid. Base Units of Metric Measurement Three base units are commonly used for metric measurement of medications to indicate weight (or mass), volume, and length: gram (), liter (), and meter ().. Memorize these base units of measurement. The litre (British and Commonwealth spelling) or liter (American spelling) (SI symbols L and l, other symbol used: ℓ) is a metric unit of volume. A litre is a cubic decimetre, which is the volume of a cube 10 centimetres × 10 centimetres × 10 centimetres (1 L ≡ 1 dm3 ≡ 1000 cm3). There is only one common abbreviations of liter: “L”. [4] (Eds.). One cubic foot has an exact volume of 28.316846592 litres, which is 4.88% higher than the 27-litre approximation. The metric system is not widely used in the U.S., but most of the rest of the world does use it. Water providers are required to sample for lead in drinking water, and the most recent samples taken by the Little Thompson district came back with 11 that exceeded 15 micrograms per liter. One cubic foot would contain exactly 27 such cubes (four inches on each side), making one cubic foot approximately equal to 27 litres. The liter is abbreviated with the unit symbol (L). The internationally accepted abbreviation for liter is the letter l; however, this can be confused with the numeral 1, especially in typescript. Taylor, B.N. Most English abbreviations use periods as part of the abbreviated form. Kenneth Butcher, Linda Crown, Elizabeth J. Gentry (2006), International Bureau of Weights and Measures, National Institute of Standards and Technology, International Committee for Weights and Measures, Bureau International des Poids et Mesures, Bureau International des Poids et Mesures, 2006, "Décret relatif aux poids et aux mesures du 18 germinal an 3 (7 avril 1795)", "List of physicochemical data concerning water", NIST Standard Reference Database Number 69, The International System of Units (SI) – Conversion Factors for General Use, "Table 6. When this happens the water district is required to alert customers of the results and health risks of exposure to lead. When they are preceded by a figure, t… 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. This symbol can still be encountered occasionally in some English-speaking and European countries like Germany, and its use is ubiquitous in Japan and South Korea. The abbreviation "cc" is still commonly used in many fields, including medical dosage and sizing for combustion engine displacement. Never add a plural sto an abbreviated unit of measure (eg, 10 lb; not 10 lbs). The exception is liter, which IN THE UNITED STATES they recommend L to avoid confusion between the letter "l" and the number "1." This caused some concern, especially in the medical community. The litre (international spelling) or liter (American spelling) (SI symbols L or l, commonly, but incorrectly, abbreviated as ltr) is an SI accepted metric system unit of volume equal to 1 cubic decimetre (dm3), 1,000 cubic centimetres (cm3) or 1/1,000 cubic metre. It is a commonly used measure, especially in medicine, cooking and automotive engineering. (December 2003). One milliliter is 0.001 liter. ter (L, l), ( lē'tĕr ), Although the SI unit of volume is the cubic meter and, by extension, the cubic centimeter (1 cm 3 =0.000 001 m 3 ), 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. Prior to 1979, the symbol ℓ came into common use in some countries;[citation needed] for example, it was recommended by South African Bureau of Standards publication M33 and Canada in the 1970s. Passion. One litre is the volume of a cube with 10 cm sides. Examples: m (meter) The capitalized version is more easily recognized by a wider group. For example, in Canada, Australia, and New Zealand, consumer beverages are labelled almost exclusively using litres and millilitres. A litre is equal in volume to the millistere, an obsolete non-SI metric unit customarily used for dry measure. 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. Acronyms are distinguished by the fact that they are read aloud as a single word, while initialisms are spoken aloud as individual letters rather than a … Being music makers ourselves, we love geeking out on all things gear. The Metric Conversion Act of 1985 gives the, Isotopic composition and temperature per London South Bank University’s. In 1964, the definition relating the litre to mass was superseded by the current one. By international standards, liter should be abbreviated simply as “l” or “L”, with no period following. In some computer typefaces, the two characters are barely distinguishable. The symbol for litre or liter is l, but is often written as L to prevent it from looking like the digit 1. (2006). Acronyms and initialisms are abbreviations of multiple words using just their initial letters; like the initials of a person’s name, these letters are usually capitalized.

It is also sometimes rendered in lowercase cursive form ℓ for the same reason: The litre, and the symbol lower-case l, were adopted by the CIPM in 1879 (PV, 1879, 41). Use of a plural sis acceptable for units that are unabbreviated, such as acre or rad. All units and prefixes should be spelled as shown in this guide. These end up in landfills. One litre of liquid water has a mass of almost exactly one kilogram, due to the gram being defined in 1795 as one cubic centimetre of water at the temperature of melting ice. In countries where the metric system was adopted as the official measuring system after the SI standard was established, common usage eschews prefixes that are not powers of 1000. Other units may be found in the table below, where the more often used terms are in bold. SI unit of litre is abbreviated as 'L'. A mnemonic for its volume relative to an imperial pint is "a litre of water's a pint and three quarters"; this is very close, as a litre is actually 1.75975399 pints. However, it should be noted that "mL" is also a valid abbreviation for milliliter. The litre was introduced in France in 1795 as one of the new "republican units of measurement" and defined as one cubic decimetre. The word liter is derived from the French word litron, which is an archaic measurement for grain. 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. In colloquial Dutch in Belgium, a "vijfentwintiger" and a "drieëndertiger" (literally "twenty-fiver" and "thirty-threer") are the common beer glasses, the corresponding bottles mention 25 cL and 33 cL. In spoken English, the symbol "mL" (for millilitre) can be pronounced as "mil". Inspiration. 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. Start studying Quiz 1 - Metric System and Conversions. The capitalized version is more easily recognized by a wider group. 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. Examples: meter, liter, and deka, NOT metre, litre, and deca. [citation needed], As a result, L (uppercase letter L) was adopted as an alternative symbol for litre in 1979. A popular soda can size is two liters. This can potentially cause confusion with some other measurement words such as: However the context is usually sufficient hint — "mL" is a unit of volume; whereas the others are units of linear or angular measurement. According to them (page 24) all units should have lowercase abbreviations except when the first letter is also capitalized. [citation needed] Larger volumes are usually given in cubic metres (equivalent to 1 kL), or thousands or millions of cubic metres. Define liter. 1. It follows, therefore, that 1000th of a litre, known as one millilitre (1 mL), of water has a mass of about 1 g; 1000 litres of water has a mass of about 1000 kg (1 tonne). This entry refers not to a or an as abbreviations but to which of the two indefinite articles should precede a given abbreviation.

The first name of the litre was "cadil"; standards are shown at the Musée des Arts et Métiers in Paris.[12]. Also, the plural abbreviation of liter is understood by the same abbreviation, without adding an “s”, so the plural would be simply “L” or “l”. In the UK and Ireland, as well as the rest of Europe, lowercase l is used with prefixes, though whole litres are often written in full (so, "750 ml" on a wine bottle, but often "1 litre" on a juice carton). on store shelves.

Visualize a liter as one square meter that is millimeter thick. Start studying dosage calculation chapter 6. It is also generally for all volumes of a non-liquid nature. Bottles may also be 75 cL or half size at 37.5 cL for "artisanal" brews or 70 cL for wines or spirits. The choice depends not on the first letter of the abbreviation itself but on the sound of the first letter. The spelling "liter" is predominantly used in American English. The word litre is derived from an older French unit, the litron, whose name came from Greek—where it was a unit of weight, not volume[2]—via Latin, and which equalled approximately 0.831 litres. Definition of Quart: Quart is defined as a United States liquid unit equal to 32 fluid ounces; four quarts equal one gallon.

(Deputy Director of the National Institute of Standards and Technology). It is equal to 1 cubic decimetre (dm ), 1000 cubic centimetres (cm ) or 0.001 cubic metre (m ). [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. The original decimetre length was 44.344 lignes, which was revised in 1798 to 44.3296 lignes. Measures of mass or weight of types of tons are usually capitalized when abbreviated. In general, most abbreviations of technical terms are capitalized, but there are notable exceptions such as ac, dc, and rms. … One litre of water has a mass of almost exactly one kilogram when measured at its maximal density, which occurs at about 4 °C. Owing to the force of tradition, one noncoherent unit, the liter, equal to 10 −3 m 3, or 1 dm 3, is generally accepted for use with SI. Information. Lower-case letters are preferable because they are quicker and easier to read and do not interrupt the word-flow by making the eyes move up and down. The litre (British and Commonwealth spelling) or liter (American spelling) (SI symbols L and l,[1] other symbol used: ℓ) is a metric unit of volume. In 1879, the CIPM adopted the definition of the litre, with the symbol l (lowercase letter L). Hence 'mL' which stands for millilitre is a derived SI unit. The plural forms are liters or litres, the accepted abbreviation is L, capitalized … Additionally, the mass–volume relationship of water (as with any fluid) depends on temperature, pressure, purity and isotopic uniformity. 3 L = 3 L 3L = 3000 mlThere are 1000 milliliters in 1 liter. Note: Liter is often seen incorrectly abbreviated as ltr. Subsequent redefinitions of the metre and kilogram mean that this relationship is no longer exact.[4]. It was subsequently discovered that the cylinder was around 28 parts per million too large and thus, during this time, a litre was about 1.000028 dm3. In 1964, at the 12th CGPM conference, the original definition was reverted to, and thus the litre was once again defined in exact relation to the metre, as another name for the cubic decimetre, that is, exactly 1 dm3. You might abbreviate the word liter to L on any written measurement directions or on a bottle of soda. [13] (2008a). The unit is spelled liter in the U.S. and litre in Britain; there are many other spellings in various languages (see Spelling of Metric Units).
