Joules to Kilojoules (J to kJ) Conversion

Joules to kilojoules (J to kJ) conversion table shows the most common values for the quick reference. Alternatively, you may use the converter to convert any other values.

1 Joule (J) = 0.001 Kilojoules (kJ)

Joule is metric system energy unit (electrical, mechanical or thermal) and defined as the amount of work done by a force of one newton to move an object one meter or a current of one ampere when passing through one ohm resistance for one second. It is named after James Prescott Joule in 19th century. The abbreviation is "J".

Kilojoule is 1000 times of the amount of work done by a force of one newton to move an object one meter. The abbreviation is "kJ".
