Megaton
Before the atomic bomb, most bombs were based on explosives similar to
TNT. Therefore the explosive power of atomic bombs is compared to the
equivalent weight in TNT. A one ton explosive force is equivalent to 2,000
pounds of TNT. One megaton is equivalent to 1 million tons or 2 billion
pounds of TNT.
Using Einstein's relationship between matter and energy, one megaton
of energy would be released if about 50 grams of matter was completely
converted into energy.
