Convert j to kiloton
Joule
The joule (/dʒaʊ,dʒuːljawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).
Kiloton
The kiloton (kt) is a unit of mass equal to 1,000 metric tons (1 × 10⁶ kilograms), or alternatively a unit of energy equal to the explosive yield of 1,000 tons of TNT (approximately 4.184 × 10¹² joules). In the context of nuclear weapons, the kiloton is used to express the explosive yield of atomic bombs. The atomic bomb dropped on Hiroshima in 1945 had a yield of approximately 15 kilotons.
