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 its 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). </P> <P> In terms firstly of base SI units and then in terms of other SI units: </P>
