The "kiloton (of TNT equivalent)" is a unit of energy equal to 4.184 terajoules (4.184 × 10 12 J). [2] 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 ...
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).
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.

Diagram of a 4,000 lb HC Mark I bomb Standard American AN-M56 4,000 lb (1.8 t) general-purpose bomb. Blockbuster bombs were the RAF's high capacity (HC) bombs. Their especially thin casings allowed them to contain approximately three-quarters of their weight in explosive, with a 4,000 lb bomb (nominal weight) containing about 3,000 lb (1,400 kg) Amatol, RDX or Torpex.
In most US cities, a city block is between 1 ⁄ 16 and 1 ⁄ 8 mi (100 and 200 m). In Manhattan, the measurement "block" usually refers to a north–south block, which is 1 ⁄ 20 mi (80 m). Sometimes people living in places (like Manhattan) with a regularly spaced street grid will speak of long blocks and short blocks.
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).
The reaction of 1 kg of antimatter with 1 kg of matter would produce 1.8 × 10 17 J (180 petajoules) of energy (by the mass–energy equivalence formula, E=mc 2), or the rough equivalent of 43 megatons of TNT – slightly less than the yield of the 27,000 kg Tsar Bomba, the largest thermonuclear weapon ever detonated.
Under the UN Dangerous Goods classification, explosive hazard Divisions are awarded using the UN Manual of Criteria and Tests, by following the process flow chart '10.3 Procedure for assignment to a division of the class of explosives' and conducting the appropriate tests either UN series 5, series 6, or series 7 tests.
