TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules ( 1 gigacalorie ), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.

1000 kg. The tonne ( / tʌn / ⓘ or / tɒn /; 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 ).
The British thermal unit ( Btu) is a measure of heat, which is a form of energy. It was originally defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It is also part of the United States customary units. [1] The SI unit for energy is the joule (J); one Btu equals about 1,055 J ...
[1] The long or imperial hundredweight of 8 stone or 112 pounds (50.80 kg) is defined in the British imperial system. [2] Under both conventions, there are 20 hundredweight in a ton, producing a "short ton" of 2,000 pounds (907.2 kg) and a "long ton" of 2,240 pounds (1,016 kg).
The long ton, [1] also known as the imperial ton or displacement ton, [1] [2] is a measurement unit equal to 2,240 pounds (1,016.0 kg). It is the name for the unit called the "ton" in the avoirdupois system of weights or Imperial system of measurements. It was standardised in the 13th century. It is used in the United States for bulk commodities.
Twenty hundredweight equals a ton (as in the US and Canadian [36] systems). The imperial hundredweight is 12% greater than the US and Canadian one. The imperial ton (or long ton) is 2240 pounds, which is much closer to a tonne (about 2 204.6 pounds), compared to the 10.7% smaller North American short ton of 2 000 pounds (907.185 kg ...
The tonne (t) is an SI-compatible unit of mass equal to a megagram ( Mg ), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes. For example, a gigagram ( Gg) or 10 9 g is 10 3 tonnes, commonly called a kilotonne .
