Information AboutMegaton |
|
The kiloton or '''megaton of TNT''' is used as a unit of Energy , approximately equivalent to the energy released in the detonation of this amount of TNT . The megaton of TNT has traditionally been used to rate the energy output, and hence destructive power, of Nuclear Weapon s. This unit is written into various arms control treaties, and gives a sense of destructiveness as compared with ordinary explosives, like TNT. More recently, it has been used to describe the energy released in other highly destructive events, such as Asteroid impacts.
This definition is a conventional one. Explosives energy is normally calculated using the thermodynamic work energy of detonation, which for TNT has been accurately measured at 1120 cal/g from large numbers of air blast experiments and theoretically calculated to be 1160 cal/g, according to standard reference book ''Explosives Engineering'' (pp 406). The measured pure heat output of a gram of TNT is only 652 thermochemical calories = 2724 J {Link without Title} , but this is not the important value for explosive blast effects calculations.
