Please provide values below to convert Joule [J] to Kilojoule [kJ], or vice versa.
1 Joule (J) = 0.001 Kilojoule (kJ)
1 Kilojoule (kJ) = 1,000 Joule (J)
Example: convert 15 Joule (J) to Kilojoule (kJ):
15 Joule (J) = 15 × 0.001 Kilojoule (kJ) = 0.015 Kilojoule (kJ)
The joule (J) is the SI unit of energy, equal to the work done by a force of one newton over one meter.
