To convert joules to kilojoules, enter the value in the first field. The result in kilojoules is calculated automatically using the exact conversion factor.

1 J = 0.001 kJ
1 kJ = 1000 J

Formula: kJ = J × 0.001
J = kJ × 1000

Definitions: 1 kJ = 1000 J

The joule (J) is the SI unit of energy and work: the energy of one newton acting over one meter, or of one watt working for one second. It is a small unit, roughly the energy needed to lift a small apple by one meter.

The kilojoule (kJ) is 1,000 joules. It is used for food energy on nutrition labels in Australia, New Zealand and Europe, often next to kcal, and for reaction energies in chemistry.

See the conversion table with commonly used values, handy for quick reference or study.
