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.
Total weight of nuclear material and bomb was 98.8 - 100.2 kg Hiroshima's "Little Boy" gravity bomb: 13–18 54–75 Gun type uranium-235 fission bomb (the first of the two nuclear weapons that have been used in warfare). 64 kg of Uranium-235, about 1.38% of the uranium fissioned Nagasaki's "Fat Man" gravity bomb 19–23 79–96
Prefixes are used: kiloton(ne), megaton(ne), gigaton(ne), especially for expressing nuclear weapon yield, based on a specific combustion energy of TNT of about 4.2 MJ/kg (or one thermochemical calorie per milligram). Hence, 1 t TNT = approx. 4.2 GJ, 1 kt TNT = approx. 4.2 TJ, 1 Mt TNT = approx. 4.2 PJ. The SI unit of energy is the joule. One ...
A megaton of TNT (1,000,000 tonnes ... A less common usage is the power required to cool 1 long ton (2,240 lb or 1,016 kg = 1 long ton or 1.120 short tons or 1.016 t ...
The 1 megaton yield weapon was in service between 1980 and 1996. The 90 TN-61 warheads were produced to arm 64 M20 SLBM and 18 SSBS S3D IRBM in plateau d'albion. Another 8 warheads were used for spare parts.
A B83 casing. The B83 is a variable-yield thermonuclear gravity bomb developed by the United States in the late 1970s that entered service in 1983. With a maximum yield of 1.2 megatonnes of TNT (5.0 PJ), it has been the most powerful nuclear weapon in the United States nuclear arsenal since October 25, 2011 after retirement of the B53. [1]
Scientists at San Jose State University say that a large fire that burned at a battery plant in Monterrey County, California earlier this month has left heightened levels of heavy metals in a ...
An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.
