## Units of mass

There are three similar units of mass called the ton:

1. long ton (simply ton in countries such as the United Kingdom which formerly used the Imperial system of weights and measures) is a weight ton or gross ton, and is 2,240 pounds (exactly 1,016.0469088 kg). Mass is a fundamental concept in Physics, roughly corresponding to the Intuitive idea of how much Matter there is in an object The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located Imperial units or the Imperial system is a collection of units first defined in the British Weights and Measures Act of 1824 To help compare different orders of magnitude, the following list describes various Mass levels between 10&minus36&thinsp kg and 1053&thinspkg In the UK and most of the areas which used the Imperial system, the metric ton (1,000 kg), which it is conveniently very similar to—less than 2% difference—is the only form of ton legal for trade. This article is about the tonne or metric ton For other tons see Ton.
• In the iron industry in the 17th century and 18th century, a ton shortweight was the standard 2,240 lb, whereas a ton longweight was 2,400 lb (the hundredweight being 120 lb).
• The long ton is used for petroleum products such as aviation fuel. Aviation fuel is a specialized type of Petroleum -based fuel used to power Aircraft.
• Deadweight ton (abbreviation 'DWT' or 'dwt') is a measure of a ship's carrying capacity, including bunker oil, fresh water, ballast water, crew and provisions. It is expressed in metric tons (1,000 kg) or long tons (2,240 pounds, about 1,016 kg)[1]. This measurement is also used in the U. S. tonnage of naval ships.
• Increasingly, metric tonnes are being used rather than long tons in measuring the displacement of ships. This article is about the tonne or metric ton For other tons see Ton. See tonnage. Tonnage is a measure of the size or Cargo capacity of a Ship.
2. short ton (usually called simply ton in North America or sometimes called a net ton) = 2,000 lb (about 907.18474 kg). The short ton ( S/T) is a unit of mass equal to 2000 lb (around 907 To help compare different orders of magnitude, the following list describes various Mass levels between 10&minus36&thinsp kg and 1053&thinspkg
• Harbour ton used in South Africa in the 20th century, equal to 2000 pounds or one short ton. The Republic of South Africa (also known by other official names) is a country located at the southern tip of the continent of Africa
3. metric ton, often referred to as a tonne, is 1,000 kg (or 1 Mg) or approximately 2,204. This article is about the tonne or metric ton For other tons see Ton. 1 E3 may refer to The integer 1000 The chess opening move 1e3 Van 't Kruijs Opening 6 pounds.

Both the long ton and the short ton are composed of twenty hundredweights, each having different values for the hundredweight (112 and 100 pounds respectively). Hundred weight or hundredweight is a Unit of measurement for Mass in U Prior to the 15th century in England, the ton was composed of 20 hundredweights, each of 108 lb, giving a ton of 2,160 pounds. England is a Country which is part of the United Kingdom. Its inhabitants account for more than 83% of the total UK population whilst its mainland

Assay ton (abbreviation 'AT') is not a unit of measurement (nobody ever has x assay tons of something), but rather a standard quantity used in assaying ores of precious metals; it is 2916 grams (short assay ton) or 3223 grams (long assay ton), the amount which bears the same ratio to a milligram as a short or long ton bears to a troy ounce. An assay is a procedure where a property or concentration of an Analyte is measured Troy weight is a system of units of Mass customarily used for Precious metals Black powder, and Gemstones Named after Troyes In other words, the number of milligrams of a particular metal found in a sample of this size gives the number of troy ounces contained in a short or long ton of ore.

In documents that predate 1960 the word ton is sometimes spelled tonne; however, in more recent documents the spelling tonne refers exclusively to the metric ton. This article is about the tonne or metric ton For other tons see Ton.

In the context of nuclear power plants, tHM and MTHM mean (metric) tonnes of heavy metals, and MTU means metric tonnes of uranium. Nuclear power is any Nuclear technology designed to extract usable Energy from atomic nuclei via controlled Nuclear reactions Uranium (jʊˈreɪniəm is a silvery-gray Metallic Chemical element in the In the steel industry, the acronym THM has the meaning 'tons/tonnes hot metal', which refers to the amount of liquid iron or steel that is produced (particularly in the context of blast furnace production or specific consumption). Steel is an Alloy consisting mostly of Iron, with a Carbon content between 0 A blast furnace is a type of metallurgical Furnace used for Smelting to produce metals generally Iron.

A dry ton or dry tonne has the same mass value, but the material (sludge, slurries, compost, and similar mixtures in which solid material is soaked with or suspended in water) has been dried to a relatively low, consistent moisture level (dry weight). SLUDGE (Scripting Language for Unhindered Development of a Gaming Environment is a open source adventure game engine developed by Hungry Software Compost (ˈkɒmpɒst or US /ˈkɒmpoʊst/ also known as brown manure is the aerobically decomposed remnants of Organic matter. Water is a common Chemical substance that is essential for the survival of all known forms of Life. If the material is in its natural, wet state, it is called a wet ton or wet tonne.

## Common abbreviations

In the U. S. mining industry, 'T' is used to distinguish the traditional ton from the metric ton, but 'T' is also the SI symbol for the tesla. The tesla (symbol T) is the SI derived unit of Magnetic field B (which is also known as "magnetic flux density" and "magnetic The symbol 't', traditionally used for the long or short ton, is now reserved for the metric ton.

## Units of force

There are also the units of force based on each of these three mass units, but none are acceptable for use with SI. The tonne force, like the kilogram force, is no exception. Only the tonne as a unit of mass is acceptable for use with SI.

• 1 short ton force = 2000 pounds-force (lbf) = 8. This article deals with the unit of force For the unit of mass see Pound (mass. 896443230521 kilonewtons (kN)
• 1 long ton force = 2240 lbf = 9. The newton (symbol N) is the SI derived unit of Force, named after Isaac Newton in recognition of his work on Classical 96401641818352 kN
• 1 tonne force = 1000 kgf = 9. The unit kilogram-force ( kgf, often incorrectly just kg) or kilopond ( kp) is defined as the Force exerted by Earth's gravity 80665 kN

## Units of volume

Also see tonnage. Tonnage is a measure of the size or Cargo capacity of a Ship.

The freight ton or measurement ton is a unit of volume used for describing ship capacities (tonnage) or cargo. A ship /ʃɪp/ is a large vessel that floats on water Ships are generally distinguished from Boats based on size Tonnage is a measure of the size or Cargo capacity of a Ship. One measurement ton is equal to:

• 40 cubic feet
• 1. The cubic foot is an imperial and US customary (non- metric) unit of Volume, used in the United States Canada and the United Kingdom 481(481) cubic yards (the "481" digit sequence repeats infinitely)
• 1,132. A cubic yard is an Imperial / US customary (non- SI non- metric) unit of Volume, used in the United States, Canada and 67386368 litres
• 1. The litre or liter (see spelling differences) is a unit of Volume. 13267386368 cubic metres

The measurement ton is abbreviated as M/T, MT, or MTON, which can cause it to be confused with the metric ton or megaton. CM3 redirects here If you were looking for the 3rd game in the Cooking Mama series abbreviated as CM3 see here. This article is about the tonne or metric ton For other tons see Ton.

The register ton is also a unit of volume used for the cargo capacity of a ship, defined as 100 cubic feet (roughly 2. 83 cubic metres). It is often abbreviated GRT for gross registered ton. It is known as a tonneau de mer in Belgium, but, in France, a tonneau de mer is 1. 44 cubic metres or about 1. 88 cubic yards.

The Panama Canal net ton, a unit of volume used for billing for ships going through the Panama Canal, is the same as the register ton. The Panama Canal is a man-made Canal in Panama which joins the The fee for example in the 1990s was roughly a couple USD for each unit. The United States dollar ( sign: \$; code: USD) is the unit of Currency of the United States; it has also been

The water ton was formerly used in Great Britain and equal to 224 imperial gallons (the volume occupied by a mass of one long ton under the conditions which define the imperial gallon). Imperial units or the Imperial system is a collection of units first defined in the British Weights and Measures Act of 1824

See 1 E-1 m³ and orders of magnitude (volume) for a comparison with other volumes. To help compare different Orders of magnitudes this page lists Volumes from at 10-1 m³ to 1 m³ The pages linked in the right-hand column contain lists of volumes that are of the same order of magnitude (power of ten

(Note that volume tons are units of convenience used in shipping and are not useful in science except that they are exactly defined. )

## Units of energy and power

### Ton of TNT

Main article: TNT equivalent
• A ton of TNT or tonne of TNT is a unit of energy equal to 109 (thermochemical) calories, also known as a gigacalorie (Gcal), equal to 4. This article is about the unit of energy For its use in Nutrition and Food labelling regulations, see the article on Food energy. 184 gigajoules (GJ). The joule (written in lower case ˈdʒuːl or /ˈdʒaʊl/ (symbol J) is the SI unit of Energy measuring heat, Electricity
• A kiloton of TNT or kilotonne of TNT is a unit of energy equal to 1012 calories, also known as a teracalorie (Tcal), equal to 4. 184 terajoules (TJ).
• A megaton of TNT (1,000,000 metric tonnes) or megatonne of TNT is a unit of energy equal to 1015 calories, also known (infrequently) as a petacalorie (Pcal), equal to 4. 184 petajoules (PJ).

Note that these are small calories (cal). The dietary Calorie (Cal) is distinct and equal to one kilocalorie.

Early values for the explosive energy released by trinitrotoluene (TNT) ranged from 900 to 1100 calories per gram. Trinitrotoluene ( TNT) is a Chemical compound with the formula C6H2(NO23CH3 In order to standardise the use of the term TNT as a unit of energy, an arbitrary value was assigned based on 1000 calories (1 kcal, 4. 184 kilojoules) per gram. The joule (written in lower case ˈdʒuːl or /ˈdʒaʊl/ (symbol J) is the SI unit of Energy measuring heat, Electricity Thus there is no longer a direct connection to the chemical TNT itself. It is now merely a unit of energy that happens to be expressed using words normally associated with mass (e. g. kilogram, tonne, pound). [2] [3] The definition applies for both spellings: ton of TNT and tonne of TNT.

Measurements in tons of TNT have been used primarily to express nuclear weapon yields, though they have also been used since in seismology as well. The explosive yield of a nuclear weapon is the amount of Energy, called the Yield, discharged when a Nuclear weapon is detonated expressed usually Seismology (from Greek grc σεισμός seismos, "earthquake" and grc -λογία -logia) is the scientific study of Earthquakes

### Ton of coal equivalent

• A ton of coal equivalent or tonne of coal equivalent (TCE), a conventional value of 7 Gcal (IT) = 29. 3076 GJ.

### Ton of oil equivalent

• A ton of oil equivalent or tonne of oil equivalent (TOE), a conventional value of 10 Gcal (IT) = 41. The tonne of oil equivalent ( toe) is a unit of energy: the amount of energy released by burning one Tonne of Crude oil, approximately 42 868 GJ ≈ 10. 0067 ton of TNT. See also GTOE. 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

### Refrigeration

The unit ton is used in refrigeration and air conditioning to measure heat absorption. An air conditioner is an Appliance, System, or mechanism designed to extract Heat from an area via a Refrigeration cycle Prior to the introduction of mechanical refrigeration, cooling was accomplished by delivering ice. Installing one ton of refrigeration replaced the daily delivery of one ton of ice.

• In North America, a standard ton of refrigeration is 12,000 BTU/h = 200 BTU/min ≈ 3. 517 kW. The watt (symbol W) is the SI derived unit of power, equal to one Joule of energy per Second. It is approximately the power required to cool 1 short ton of water by 1 °F every 10 minutes; or the power required to melt one short ton (2,000 lb) of ice at 0 °C in 24 hours. Fahrenheit is a temperature scale named after Daniel Gabriel Fahrenheit (1686–1736 a German Physicist who proposed it in 1724 The pound or pound-mass (abbreviation lb, lbm, or sometimes in the United States #) is a unit of Mass
• A ton is also a unit of energy equal to that power for a period of a day, or 24 h × 12,000 BTU/h = 288,000 BTU ≈ 303. 9 megajoules. The joule (written in lower case ˈdʒuːl or /ˈdʒaʊl/ (symbol J) is the SI unit of Energy measuring heat, Electricity
• A less common usage is the power required to cool 1 long ton of water by 1 °F every 10 minutes = 13,440 BTU/h ≈ 3,939 W. The watt (symbol W) is the SI derived unit of power, equal to one Joule of energy per Second. [4][5][6]

## Truck classes

Main article: Truck classification

When light-duty trucks were first produced, they were rated by their payload capacity in tons (e. Commercial truck classification in the United States is done based on the vehicle's Gross Vehicle Weight Rating. g. , 12-, 34- and 1-ton). The Ford F-150, Chevy/GMC 1500, and Dodge 1500 are a 12-ton. The Ford F-250, Chevy/GMC 2500, and Dodge 2500 are a 34-ton. The Ford F-350, Chevy/GMC 3500, and Dodge 3500 are a 1-ton. But throughout the years, the payload capacities have increased while the ton title has stayed the same. The current ton rating scheme is nothing more than just a generic truck name.

## Miscellaneous tons

• Ton is also used informally to mean a large amount of something (material or not), for example, "We've been having a ton of good luck recently".
• In Britain, ton is colloquially used to refer to 100 of a given unit. Ton can thus refer to the speed of motor vehicles, namely to the speed of 100 miles per hour e. A motor Vehicle is a Machine which incorporates a motor (sometimes known as an Engine) and which is used for Transportation g. "Lee was doing a ton down the motorway", to money e. g. "How much did you pay for that?" "A ton" (£100), to 100 points in a game e. g. "Eric just threw a ton in our darts game" or to a hundred of pretty much anything else.

A ton is also equivalent to 100 runs in the game of cricket (more commonly known as a century).
