TNT equivalent[¦te‚en¦tē i′kwiv·ə·lənt]
the mass of a conventional charge of a chemical explosive—trinitrotoluene, or TNT—whose energy of explosive decomposition is equal to the energy released in a given nuclear explosion. The TNT equivalent characterizes the explosive power of nuclear and thermonuclear charges and is calculated according to the formula
where Qne is the energy released in the nuclear explosion and QTNT is the explosive energy of 1 ton of trinitrotoluene; it is measured in kilotons and megatons.
