Convert tonnes of TNT to joules

Explanation

From this page you can convert tonnes of TNT to joules (or tnt to J) simply, by using the application above.

In case you are wondering, to convert from tonnes of TNT to joules you need to multiply by 4184000000. This factor is calculated using the respective definitions of the two units you can find below.

Formula

1 tnt=4184000000 J

tonnes of TNTtnt

dimension	energy
symbol	tnt, t

The tonne of TNT (tnt, t) equivalent is a unit of energy.

It is based on the energy released by the detonation of a tonne (1000 kg) of TNT but not exactly the same, the exact amount of energy released varies with the circumtances of the detonation. Because of this and for practical reasons, the tonne of TNT equivalent has been normalized to a fixed value in joules, the SI unit of energy.

Definition of the tonne of TNT

The tonne of TNT equivalent has been defined as being equal to 4184000000 joules.

Definition of the joule

Le joule est le travail produit par un newton dont le point d'application se déplace de un mètre dans la direction de la force.

9^th CGPM (1948) p. 113

That is to say, one joule is the work done by a force of one newton whose point of application moves one meter in the direction of the force.
