Webjoule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds. In electrical terms, the joule equals one watt-second—i.e., the energy released in one second … WebHence, it has a value of one volt, 1 J/C, multiplied by the elementary charge e = 1.602 176 634 × 10 −19 C. Therefore, one electronvolt is equal to 1.602 176 634 × 10 −19 J. The electronvolt (eV) is a unit of energy, but is not an SI unit. The SI unit of energy is the joule (J).
