The joule (symbol J) is, according to the International System of Units, a derived unit of energy , work, or amount of heat. It is named after the English physicist, James Prescott Joule.

It is equal to the energy transferred or work done when applying one newton of force through a distance one meter (1 newton meter or N·m), or when passing an electric current of one ampere through a resistance of one ohm for one second.
It can also be defined as the amount of work required to move an electric charge of one coulomb through an electrical potential difference of one volt (1 coulomb volt or C·V), or the work required to produce one watt of power for one second (1 watt second or W·s).
