Tonnes of TNT
The tonne of TNT is defined as 4.184 GJ, about the energy released by detonating a tonne of the explosive, and is the unit of nuclear yields and of large explosions and impacts. The Hiroshima bomb was about 15 kt, the largest weapon ever tested (Tsar Bomba, 1961) 50 Mt, the 2020 Beirut explosion roughly 0.5 kt, and the Chicxulub impact that ended the dinosaurs on the order of 100 million Mt.
