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.
Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
A hand is a unit of length used to measure the height of horses. One hand is four inches, and a value of 12.3 hands represents 12 hands + 3 inches (51 inches). Output name
In spectroscopy and related fields it is common to measure energy levels in units of reciprocal centimetres. These units (cm −1 ) are strictly speaking not energy units but units proportional to energies, with h c ∼ 2 ⋅ 10 − 23 J c m {\displaystyle \ hc\sim 2\cdot 10^{-23}\ \mathrm {J} \ \mathrm {cm} } being the proportionality constant.
Here, eV (electronvolt) is a unit of energy (the kinetic energy of an electron accelerated over one volt, 1.6 × 10 −19 joules), and c is the speed of light in vacuum. Energy and mass are related through E = mc 2. This definition is useful for a linear particle accelerator when accelerating electrons.
