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.

Toquepala also produced 38,000 tons of copper cathodes from the SX/EW plant. [5] As of the end of 2009, Toquepala reported about 13 million tons of contained copper metal in proven and probable ore reserves, at an average grade of 0.47% Cu. This corresponds to 2.6 billion tons of ore at 0.47 % Cu + 0.04% Mo + 2.3 gpt Ag.
A million tons; Megaton TNT equivalent, explosive energy equal to 4.184 petajoules; megatonne, a million tonnes, SI unit of mass; Other uses.
The energy of various amounts of the explosive TNT (kiloton, megaton, gigaton) is often used as a unit of explosion energy, and sometimes of asteroid impacts and violent explosive volcanic eruptions. One ton of TNT produces 4.184 × 10 9 joules, or (by arbitrary definition) exactly 10 9 thermochemical calories (approximately 3.964 × 10 6 BTU ...
The amount is nominal, usually 1 or 2 percent, sometimes a bit more, of the intrinsic value to the owner of the thing salved. But the thing salved off Palomares was a thermonuclear bomb, the same bomb valued by no less an authority than the Secretary of Defense at $2 billion—each percent of which is, of course, $20 million.
