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 .
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.
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 ...
This is a compilation of published detonation velocities for various high explosive compounds. Detonation velocity is the speed with which the detonation shock wave travels through the explosive.
The net explosive quantity (NEQ), also known as net explosive content (NEC) or net explosive weight (NEW), of a shipment of munitions, fireworks or similar products is the total mass of the contained explosive substances, without the packaging, casings, bullets etc. [1] It also includes the mass of the TNT-equivalent of all contained energetic substances.
Thermonuclear bombs can be hundreds or thousands of times stronger than their atomic counterparts. Due to this, thermonuclear bombs' yields are usually expressed in megatons which is about the equivalent of 1,000,000 tons of TNT. In contrast, atomic bombs' yields are typically measured in kilotons, or about 1,000 tons of TNT.
There is no exact definition of the "tactical" category in terms of range or yield of the nuclear weapon. [ 2 ] [ 3 ] The yield of tactical nuclear weapons is generally lower than that of strategic nuclear weapons, but larger ones are still very powerful, and some variable-yield warheads serve in both roles.
Energy released by explosion of 1 ton of TNT. 4.5×10 9 J: Average annual energy usage of a standard refrigerator [142] [143] 6.1×10 9 J: ≈ 1 bboe (barrel of oil equivalent) [144] 10 10 1.9×10 10 J: Kinetic energy of an Airbus A380 at cruising speed (560 tonnes at 511 knots or 263 m/s) 4.2×10 10 J: ≈ 1 toe (ton of oil equivalent) [144] 4 ...
