I want to ask, how is the equivalent of a nuclear bomb calculated? What does 1000 ton equivalent mean? How good is it? What's the killing range?

TNT equivalent refers to how many tons (t) of TNT explosive is equivalent to the energy released during a nuclear explosion. Equivalent is the corresponding value of energy generated during the explosion relative to TNT explosive. The amount of TNT explosive is also used as an energy unit, which can generate 4.2 million joules per kilogram, 1 ton TNT is equivalent to 4,200 megajoules, and 1 0,000 tons is equivalent to 4,200 gigajoules (where megajoules are computer counting units 1 megajoules = 1 * 10 6). For example, a nuclear warhead with an equivalent of 654.38+100,000 tons means that the energy generated by the explosion of this nuclear bomb is equivalent to the heat generated by the explosion of 654.38+100,000 tons of TNT explosives. The power is 4.2 million MJ, and the radius of killing range is 300 meters.
