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 ...
The energy density of TNT is used as a reference point for many other explosives, including nuclear weapons, as their energy content is measured in equivalent tonnes (metric tons, t) of TNT. The energy used by NIST to define the equivalent is 4.184 GJ/t. [24]
Other smaller tests include Air Vent I and Flat Top I-III series of 20 tons TNT at Nevada Test Site in 1963–64, Pre Mine Throw and Mine Throw in 1970–1974, Mixed Company 1 & 2 of 20 tons TNT, Middle Gust I-V series of 20 or 100 tons TNT in the early 1970s, Pre Dice Throw and Pre Dice Throw II in 1975, Pre-Direct Course in 1982, SHIST in ...
US scientists with a full-scale cut-away model of the W48, a very small tactical nuclear weapon with an explosive yield equivalent to 72 tons of TNT (0.072 kiloton). Around 100 of such shells were produced during the Cold War.
The energy of various amounts of the explosive TNT (kiloton, megaton, gigaton) is often used as a unit of explosion energy, and sometimes of asteroid impacts and violent explosive volcanic eruptions. One ton of TNT produces 4.184 × 10 9 joules, or (by arbitrary definition) exactly 10 9 thermochemical calories (approximately 3.964 × 10 6 BTU ...

The FOAB device allegedly yields the equivalent of 44 tons of TNT using about seven tons of a new type of high explosive. Because of this, the bomb's blast and pressure wave have a similar effect to a small tactical nuclear weapon. [4] The bomb works by detonating in mid-air. Thermobaric weapons differ from conventional explosive weapons in ...
