Joule to kJ

1 Joule is equal to .001 kJ. The joules and kJ are both SI units of measurement. A Joule is equal to the work done by a force of one newton acting through one metre. The Joule derives its name from English physicist James Prescott Joule. A Joule can also be expressed electrically as one watt-second. One watt-second is the energy released in one second by a current of one ampere through a resistance of one ohm. This converter can be used to convert any amount of Joule to Kilojoule.
