Note that periods are not used and the abbreviation is the same regardless of whether it A litre is the volume of a cube with sides of 10 cm, which is slightly less than a cube of sides 4 inches (one-third of a foot). Home » Abbreviations Dictionary » What is the Abbreviation for Liter? –. This page was last edited on 20 December 2020, at 19:27. A good number of scientific papers use mL as well as Joint Commission on Accreditation of Healthcare Organizations. How do you abbreviate liter? The choice depends not on the first letter of the abbreviation itself but on the sound of the first letter. 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. For example, Jean’s special fish stew calls for two quarts of clam broth. (2008a). (Eds.). One litre is the volume of a cube with 10 cm sides. The liter is abbreviated with the unit symbol (L). Examples: meter, liter, and deka, NOT metre, litre, and deca. This made the litre equal to about 1.000028 dm3 (earlier reference works usually put it at 1.000027 dm3). Units are improperly capitalized if they are named after people. (Table 6, page 20). 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). In some computer typefaces, the two characters are barely distinguishable. The exception is liter, which IN THE UNITED STATES they recommend L to avoid confusion between the letter "l" and the number "1." In many English-speaking countries, however, the most common shape of a handwritten Arabic digit 1 is just a vertical stroke; that is, it lacks the upstroke added in many other cultures. A litre of liquid water has a mass almost exactly equal to one kilogram. [8], Originally, the only symbol for the litre was l (lowercase letter L), following the SI convention that only those unit symbols that abbreviate the name of a person start with a capital letter. The Newton (after Isaac Newton) for measuring units of force The Watt (after James Watt) for measuring units of power, joules per second. The most common mistake made in abbreviating liter is using three letters. [5], The litre, though not an official SI unit, may be used with SI prefixes. Neither LTR or ltr would be a correct abbreviation. 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. Glamor or Glamour – What’s the Difference? This caused some concern, especially in the medical community. One milliliter is 0.001 liter. Because volume changes with temperature and pressure, and pressure uses units of mass, the definition of a kilogram was changed. Fonts covering the CJK characters usually include not only the script small ℓ but also four precomposed characters: ㎕, ㎖, ㎗ and ㎘ for the microlitre, millilitre, decilitre and kilolitre. 3 L = 3 L 3L = 3000 mlThere are 1000 milliliters in 1 liter. Most English abbreviations use periods as part of the abbreviated form. 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 1 litre of water referred to above. One cubic foot would contain exactly 27 such cubes (four inches on each side), making one cubic foot approximately equal to 27 litres. 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 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. It is equal to 1 cubic decimetre (dm3), 1000 cubic centimetres (cm3) or 0.001 cubic metre (m3). 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 also expressed a preference that in the future only one of these two symbols should be retained, but in 1990 said it was still too early to do so.[10]. The spelling "liter" is predominantly used in American English. One cubic foot has an exact volume of 28.316846592 litres, which is 4.88% higher than the 27-litre approximation. Learn vocabulary, terms, and more with flashcards, games, and other study tools. 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). 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 … [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. 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. [citation needed] Similarly, alcohol shots are often marked in cL in restaurant menus, typically 3 cL (1.06 imp fl oz; 1.01 US fl oz). 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. Bureau International des Poids et Mesures. The abbreviation for liter is preferably capitalized, L, to avoid confusion with the number 1.. Household System of Measurement Utensils used in the home, … The capitalized version is more easily recognized by a wider group. 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. The capitalized version is more easily recognized by a wider group. 1. The word liter functions as a noun in the sentence. Temperature abbreviations use capitals because they come from proper nouns. [6] There are two international standard symbols for the litre: L and l. In the United States the former is preferred because of the risk that (in some fonts) the letter l and the digit 1 may be confused.[7]. 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. [citation needed] Larger volumes are usually given in cubic metres (equivalent to 1 kL), or thousands or millions of cubic metres. Personal titles, however, in Spanish and English both are capitalized, so there’s no confusion there! One litre is slightly larger than a US liquid quart and slightly less than an imperial quart or one US dry quart. In 1964, the definition relating the litre to mass was superseded by the current one. 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 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. [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. The litre is often also used in some calculated measurements, such as density (kg/L), allowing an easy comparison with the density of water. Visualize a liter as one square meter that is millimeter thick. National Institute of Standards and Technology. 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. When they are preceded by a figure, t… and for measuring the size of the catch and quotas for fishing boats; decilitres are common in Croatia, Switzerland and Scandinavia and often found in cookbooks, and restaurant and café menus; centilitres indicate the capacity of drinking glasses and of small bottles. CGPM defines the litre and its acceptable symbols. [13] 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. Inspiration. Learn vocabulary, terms, and more with flashcards, games, and other study tools. From the tweakiest techniques to the biggest ideas, our experts work hard to constantly supply inSync with a steady stream of helpful, in-depth demos, reviews, how-tos, news, and interviews. 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. It is also generally for all volumes of a non-liquid nature. This abbreviation is commonly used in recipes, classrooms, and miscellaneous unit measurements. The original French metric system used the litre as a base unit. Both "l" and "L" are internationally accepted. The plural forms are liters or litres, the accepted abbreviation is L, capitalized … Capitalization (North American English) or capitalisation (British English) is writing a word with its first letter as a capital letter (uppercase letter) and the remaining letters in lower case, in writing systems with a case distinction.The term also may refer to the choice of the casing applied to text. Most Spanish abbreviations are not capitalized. ● cc ● millilitre ● cubic centimetre ● cl ● centiliter ● cubic centimeter ● metric capacity unit ● centilitre ● cubic millimeter ● mil ● cubic millimetre ● ml The Abbreviation The abbreviated form of the word liter is upper case L or lowercase letter l, but some people use a cursive ℓ to ensure that the abbreviation is not confused with the number 1 or a capital letter i. and Thompson, A. Hence 1 L ≡ 0.001 m3 ≡ 1000 cm3, and 1 m3 (i.e. Wellbeing or Well-Being – Which is Correct? There is only one common abbreviations of liter: “L”. It is equal to 1 cubic decimetre (dm ), 1000 cubic centimetres (cm ) or 0.001 cubic metre (m ). Therefore, as a general rule, capitals should not be used unless there is a good reason to do so, eg, to show the beginning of a sentence. on store shelves. 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. 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. [citation needed], As a result, L (uppercase letter L) was adopted as an alternative symbol for litre in 1979. The abbreviation "cc" (for cubic centimetre, equal to a millilitre or mL) is a unit of the cgs system, which preceded the MKS system, which later evolved into the SI system. This made the original litre 1.000974 of today's cubic decimetre. (16 May 2008). 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. (2006). In the SI system, apart from prefixes for powers of 1000, use of the "centi" (10−2), "deci" (10−1), "deca" (10+1) and "hecto" (10+2) prefixes with litres is common. Examples: m (meter) Hence 'mL' which stands for millilitre is a derived SI unit. (December 2003). Therefore, the digit "1" may easily be confused with the letter "l". [4] 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. Cans come in 25 cL, 33 cL and 50 cL. Start studying dosage calculation chapter 6. It is a commonly used measure, especially in medicine, cooking and automotive engineering. SI symbols should be preceded by digits and a space must separate the digits from the symbol. The first name of the litre was "cadil"; standards are shown at the Musée des Arts et Métiers in Paris.[12]. The word is much less common in American English than elsewhere because Americans generally use U.S. customary units rather than the metric … Definition of Liter: Liter is defined as a metric unit of capacity, formerly defined as the volume of 1 kilogram of water under standard conditions, now equal to 1,000 cubic centimeters (about 1.75 pints). An early definition of the kilogram was set as the mass of one litre of water. Start studying Quiz 1 - Metric System and Conversions. Being music makers ourselves, we love geeking out on all things gear. In addition to the unit symbols, Table II lists many common technical abbreviations in their standard IEEE editorial forms. 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. … What Does Quart Mean? 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 0.999975±0.000001 kg/L at its point of maximum density (3.984 °C) under one standard atmosphere (760 Torr = 101.325 kPa) of pressure. By international standards, liter should be abbreviated simply as “l” or “L”, with no period following. In spoken English, the symbol "mL" (for millilitre) can be pronounced as "mil". Information. 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). 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. 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. This relationship holds because the gram was originally defined as the mass of 1 mL of water; however, this definition was abandoned in 1799 because the density of water changes with temperature and, very slightly, with pressure. When to Use This Abbreviation. A litre is equal in volume to the millistere, an obsolete non-SI metric unit customarily used for dry measure. Hectolitres sometimes appear in industry, but centilitres and decilitres are rarely, if ever, used. The original decimetre length was 44.344 lignes, which was revised in 1798 to 44.3296 lignes. Capitalization When Defining Abbreviations Although an abbreviation is composed of capital letters, the full words that define the abbreviation are not always capitalized. We read by moving our eyes from right to left across a line of letters which are broken up into groups called words. It was against this litre that the kilogram was constructed. Subsequent redefinitions of the metre and kilogram mean that this relationship is no longer exact.[4]. Taylor, B.N. [14], In 1979, at the 16th CGPM conference, the alternative symbol L (uppercase letter L) was adopted. 6.1.2 Capitalization Unit symbols are printed in lower-case letters except that: (a) the symbol or the first letter of the symbol is an upper-case letter when the name of the unit is derived from the name of a person; and (b) the recommended symbol for the liter in the United States is L [see Table 6, footnote (b)]. Additionally, the mass–volume relationship of water (as with any fluid) depends on temperature, pressure, purity and isotopic uniformity. 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 (m3). Bottles may also be 75 cL or half size at 37.5 cL for "artisanal" brews or 70 cL for wines or spirits. 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.
