### Wiktionary

joule(Noun)

In the International System of Units, the derived unit of energy, work and heat; the work required to exert a force of one newton for a distance of one metre. Also equal to the energy of one watt of power for a duration of one second. Symbol: J

**Origin:** Named after the English physicist James Prescott Joule.

### Webster Dictionary

Joule(noun)

a unit of work which is equal to 107 units of work in the C. G. S. system of units (ergs), and is practically equivalent to the energy expended in one second by an electric current of one ampere in a resistance of one ohm. One joule is approximately equal to 0.738 foot pounds

### Freebase

Joule

The joule, symbol J, is a derived unit of energy, work, or amount of heat in the International System of Units. It is equal to the energy expended in applying a force of one newton through a distance of one meter, or in passing an electric current of one ampere through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule. In terms firstly of base SI units and then in terms of other SI units: where N is the newton, m is the meter, kg is the kilogram, s is the second, Pa is the pascal, and W is the watt. One joule can also be defined as: ⁕The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one '"coulomb volt". This relationship can be used to define the volt. ⁕The work required to produce one watt of power for one second, or one "watt second". This relationship can be used to define the watt.

### The Standard Electrical Dictionary

Joule

This term has been applied to several units. (a) The practical C. G. S. unit of electric energy and work--the volt-coulomb. It is equal to 1E7 ergs--0.73734 foot pound.--.00134 horse power seconds. A volt-ampere represents one joule per second. (b) It has also been used as the name of the gram-degree C. thermal unit--the small calorie. Synonym--Joulad.
