The joule is the SI unit of energy.


It is defined as being:

the energy transferred to (or work done on) a body when a force of $1$ newton acts on that body in the direction of the force's motion through a distance of $1$ metre
the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second.

Thus:

$1 \, \mathrm J = 1 \, \mathrm N \, \mathrm m$
\(\ds \) \(\) \(\ds 1\) joule
\(\ds \) \(=\) \(\ds 10^7\) ergs
