O NUCLEAR WEAPON YIELD The explosive yield of a nuclear weapon is the amount of energy discharged when a nuclear weapon is detonated, expressed usually in the equivalent mass of tri(nitrotoluene (TNT), either in kilotons (thousands of tons of TNT) or megatons (millions of tons of TNT), but sometimes also in terajoules (1 kiloton of TNT = 4.184 TJ). Because the precise amount of energy released by TNT is and was subject to measurement uncertainties, especially at the dawn of the nuclear age, the accepted convention is that one kt of TNT is simply defined to be 1012 calories equivalent, this being very roughly equal to the energy yield of 1,000 tons of TNT.

The 50 Megaton megabomb was developed by the Soviet Union and was tested on October 30, 1961, in the Novaya Zemlya archipelago. The Tsar Bomba was the single most physically powerful device built by humans, producing approximately 1.4% of the power output of the Sun.
