Joule

An SI unit defined as the energy required equivalent to the work done when the point of application of a force of one newton moves a distance of one meter in the direction of the force.  A formally defined conversion factor is that 4.1868 joules = one calorie.  The term joule was devised by the British physicist James Precott Joule (1818-1889).
