The tonne ( / t ʌ n / or / t ɒ n / ; symbol: t ) is a unit of mass equal to 1,000 kilograms . It is a non-SI unit accepted for use with SI . It is also referred to as a metric ton in the United States to distinguish it from the non-metric units of the short ton ( United States customary units ) and the long ton ( British imperial units ). It is equivalent to approximately 2,204.6 pounds , 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram ( Mg ), a less common way to express the same amount.
22-916: A Charentais melon is a type of French cantaloupe , Cucumis melo var. cantalupensis . It is a small variety of melon, around the size of a softball. It has flesh similar to most cantaloupes, but with a distinct and more intense aroma, and a more orangey hue. It originated in the Charentes region of France, and is most associated with the Provençal area around the town of Cavaillon . Most true Charentais melons are grown in and around this region, and are almost exclusively available in France, as their thin skin and soft flesh does not do well in shipping. Hybrids of this variety are widely grown, they are generally crossed with North American cantaloupes for better shipping characteristics and larger size. The Charentais melon

Raw cantaloupe is 90% water, 8% carbohydrates , 0.8% protein and 0.2% fat (table). In a reference amount of 100 grams (3.5 oz), raw cantaloupe supplies 140 kJ (34 kcal) of food energy , and is a rich source (20% or more of the Daily Value , DV) of vitamin A (29% DV) and
66-502: A period . Use of lower case is significant, and use of other letter combinations can lead to ambiguity. For example, T, MT, mT, are the SI symbols for the tesla , megatesla, and millitesla, respectively, while Mt and mt are SI-compatible symbols for the megatonne (one teragram) and millitonne (one kilogram). If describing TNT equivalent units of energy, one megatonne of TNT is equivalent to approximately 4.184 petajoules . In English, tonne
88-677: A ton typically refers to a short ton of 2,000 lb (907.2 kg) and to a lesser extent to a long ton of 2,240 lb (1,016 kg), with the term tonne rarely used in speech or writing. Both terms are acceptable in Canadian English . Ton and tonne are both derived from a Germanic word in general use in the North Sea area since the Middle Ages (cf. Old English and Old Frisian tunne , Old High German and Medieval Latin tunna , German and French tonne ) to designate
110-536: A commercial crop in the United States. Melon derived from use in Old French as meloun during the 13th century, and from Medieval Latin melonem , a kind of pumpkin. It was among the first plants to be domesticated and cultivated . The South African English name spanspek dates back at least as far as 18th-century Dutch Suriname : J. van Donselaar wrote in 1770, " Spaansch-spek
132-418: A large cask, or tun . A full tun, standing about a metre high, could easily weigh a tonne. See also the common German word de:Mülltonne (literal translation: garbage drum ). The spelling tonne pre-dates the introduction of the SI in 1960; it has been used with this meaning in France since 1842, when there were no metric prefixes for multiples of 10 and above, and is now used as the standard spelling for
154-543: A moderate source of vitamin C (13% DV). Other micronutrients are in negligible amounts (less than 10% DV) (table). Tonne The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879. Its use is also official for the metric ton in the United States, having been adopted by the United States National Institute of Standards and Technology (NIST). It is a symbol, not an abbreviation, and should not be followed by
176-555: A result. However, the term had been in use long before that point. The true or European cantaloupe (Cantalupensis Group sensu stricto ), which has non- to slightly netted rind and orange flesh, includes the following types: The Israeli cantaloupe (Sub-group Ha'Ogen) is similar to the European one, but it has green flesh. The muskmelon or American cantaloupe (formerly Reticulatus Group but now merged into Cantalupensis Group), which has strongly netted rind and orange flesh, includes
198-445: Is an established spelling alternative to metric ton . In the United States and United Kingdom, tonne is usually pronounced the same as ton ( / t ʌ n / ), but the final "e" can also be pronounced, i.e. " tunnie " ( / ˈ t ʌ n i / ). In Australia, the common and recommended pronunciation is / t ɒ n / . In the United States, metric ton is the name for this unit used and recommended by NIST; an unqualified mention of
220-438: Is little need to distinguish between metric and other tons, and the unit is spelled either as ton or tonne with the relevant prefix attached. A metric ton unit (mtu) can mean 10 kg (22 lb) within metal trading, particularly within the United States. It traditionally referred to a metric ton of ore containing 1% (i.e. 10 kg) of metal. The following excerpt from a mining geology textbook describes its usage in
242-400: Is the joule . One tonne of TNT is approximately equivalent to 4.2 gigajoules. In the petroleum industry the tonne of oil equivalent (toe) is a unit of energy : the amount of energy released by burning one tonne of crude oil , approximately 42 GJ. There are several slightly different definitions. This is ten times as much as a tonne of TNT because atmospheric oxygen is used. Like

#1732772537845264-481: Is the mass of one cubic metre of pure water at 4 °C (39 °F). As a non-SI unit, the use of SI metric prefixes with the tonne does not fall within the SI standard. For multiples of the tonne, it is more usual to speak of thousands or millions of tonnes. Kilotonne, megatonne, and gigatonne are more usually used for the energy of nuclear explosions and other events in equivalent mass of TNT , often loosely as approximate figures. When used in this context, there
286-472: Is the most cultivated melon type in France. The shelf life of the Charentais melon is about four days. This Cucurbitales article is a stub . You can help Misplaced Pages by expanding it . Cantaloupe The cantaloupe ( / ˈ k æ n t ə l oʊ p / KAN -tə-lohp ) is a type of true melon ( Cucumis melo ) with sweet, aromatic, and usually orange flesh. Originally, cantaloupe refers to
308-563: Is the name for the form that grows in Suriname which, because of its thick skin and little flesh, is less consumed." A common etymology involves the Spanish-born Juana María de los Dolores de León Smith , who ate canteloupe for breakfast while her husband and 19th-century governor of Cape Colony , Sir Harry Smith , ate bacon and eggs; the fruit was termed Spanish bacon ( Afrikaans Spaanse spek ) by locals as
330-466: Is used as a proxy for energy, usually of explosions (TNT is a common high explosive ). Prefixes are used: kiloton(ne), megaton(ne), gigaton(ne), especially for expressing nuclear weapon yield , based on a specific combustion energy of TNT of about 4.2 MJ / kg (or one thermochemical calorie per milligram ). Hence, 1 t TNT = approx. 4.2 GJ , 1 kt TNT = approx. 4.2 TJ , 1 Mt TNT = approx. 4.2 PJ . The SI unit of energy
352-605: The true cantaloupe or European cantaloupe with non- to slightly netted and often ribbed rind. Today, it also refers to the muskmelon with strongly netted rind, which is called cantaloupe in North America (hence the name American cantaloupe ), rockmelon in Australia and New Zealand, and spanspek in Southern Africa. Cantaloupes range in mass from 0.5 to 5 kilograms (1 to 11 lb). The name cantaloupe
374-490: The Japanese muskmelon under Inodorus Group instead of Cantalupensis or Reticulatus Group. In 2016, global production of melons, including cantaloupes, totaled 31.2 million tons , with China accounting for 51% of the world total (15.9 million tons). Other significant countries growing cantaloupe were Turkey , Iran , Egypt , and India producing 1 to 1.9 million tons, respectively. California grows 75% of
396-583: The cantaloupes in the US. Cantaloupe is normally eaten as a fresh fruit, as a salad, or as a dessert with ice cream or custard. Melon pieces wrapped in prosciutto are a familiar antipasto . The seeds are edible and may be dried for use as a snack. Because the surface of a cantaloupe can contain harmful bacteria—in particular, Salmonella —it is recommended that a melon be washed and scrubbed thoroughly before cutting and consumption to prevent risk of Salmonella or other bacterial pathogens. A moldy cantaloupe in
418-473: The following types: A melon with netted rind is not necessarily a cantaloupe. Many varieties of Chandalak Group and Ameri Group also have netted rind. The Japanese muskmelon (Sub-group Earl's) resembles the American cantaloupe in netted rind, but differs in green flesh and non-dehiscent peduncles (which means the melon does not detach from the stalk when it is ripe). Therefore, some horticulturists classify
440-522: The metric mass measurement in most English -speaking countries. In the United States, the unit was originally referred to using the French words millier or tonneau , but these terms are now obsolete. The British imperial and United States customary units are comparable to the tonne and the spelling of ton in English is the same, though they differ in mass. One tonne is equivalent to: A tonne
462-482: The particular case of tungsten: Tungsten concentrates are usually traded in metric tonne units (originally designating one tonne of ore containing 1% of WO 3 , today used to measure WO 3 quantities in 10 kg units. One metric tonne unit (mtu) of tungsten (VI) contains 7.93 kilograms of tungsten. In the case of uranium , MTU is sometimes used in the sense of metric ton of uranium (1,000 kg [2,200 lb]). The tonne of trinitrotoluene (TNT)
