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. The TNT equivalent appears in various nuclear weapon control treaties, and has been ...
The blast wave spread up to 200 mi (320 km) and was estimated to have a TNT equivalent of either 200 to 240 tons or 1.3 to 1.8 kilotons of high-explosives. [ 2 ] [ 18 ] [ 11 ] Resulting fires were detected from NASA's fire monitoring systems as covering an area of approximately 13 km 2 (5 sq mi).
List of orders of magnitude for energy; Factor (joules) SI prefix Value Item 10 −34: 6.626 × 10 −34 J: Energy of a photon with a frequency of 1 hertz. [1]8 × 10 −34 J: Average kinetic energy of translational motion of a molecule at the lowest temperature reached (38 picokelvin [2] as of 2021)
Tritonal is a mixture of 80% TNT and 20% aluminium powder, used in several types of ordnance such as air-dropped bombs. The aluminium increases the total heat output and hence impulse of the TNT – the length of time during which the blast wave is positive. Tritonal is approximately 18% more powerful than TNT alone.

However, the names of all SI mass units are based on gram, rather than on kilogram; thus 10 3 kg is a megagram (10 6 g), not a *kilokilogram. The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes.
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 ...

According to Willmore, [52] the energy released was 1.3×10 13 J, or about 3.2 kilotons of TNT equivalent. The blast is listed in the Guinness Book of World Records under largest single explosive detonation , although Minor Scale in 1985 was larger (see below).
