Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
A kiloton of TNT can be visualized as a cube of TNT 8.46 metres (27.8 ft) on a side. The "megaton (of TNT equivalent)" is a unit of energy equal to 4.184 petajoules (4.184 × 10 15 J). [3] The kiloton and megaton of TNT equivalent have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon.
American AN-M64 500-lb general-purpose bomb in Boeing B-29 Superfortress weapons bay. General-purpose (GP) bombs use a thick-walled metal casing with explosive filler (typically TNT, Composition B, or Tritonal in NATO or United States service) comprising about 30% to 40% of the bomb's total weight.

While the 21,600-pound (9,797-kg) GBU-43 is billed as the U.S. military's most powerful non-nuclear bomb, its destructive power, equivalent to 11 tonnes of TNT, pales in comparison with the ...
Sycamore, a clean test, was a fizzle, producing only 92 kilotonnes of TNT (380 TJ) instead of the predicted 5 megatonnes of TNT (21 PJ). Poplar was a retest of Sycamore with a predicted yield of 5 to 10 megatonnes of TNT (21 to 42 PJ) and only 200 kilotonnes of TNT (840 TJ) fission yield. The actual yield was 9.3 megatonnes of TNT (39 PJ).
The Trinity bomb released the explosive energy of 25 kilotons of TNT (100 TJ) ± 2 kilotons of TNT (8.4 TJ), and a large cloud of fallout. Thousands of people lived closer to the test than would have been allowed under guidelines adopted for subsequent tests, but no one living near the test was evacuated before or afterward.
The W80 is a low to intermediate yield two-stage thermonuclear warhead deployed by the U.S. enduring stockpile with a variable yield ("dial-a-yield") of 5 or 150 kilotonnes of TNT (21 or 628 TJ). It was designed for deployment on cruise missiles and is the warhead used in all nuclear-armed ALCM and ACM missiles deployed by the US Air Force ...
