**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. In other words, for each gram of TNT exploded, 4.184 kilojoules (or 4,184 joules) of energy are released.
