How to convert
To convert kJ to J, multiply: J = kJ × 1,000
To convert J to kJ, divide: kJ = J ÷ 1,000 (equivalently × 0.001).
Example: 1 kJ × 1,000 = 1,000 J. The factor is derived from the international definition of each unit; results are shown to 4 significant figures.
Frequently asked questions
1 kJ = 1,000 J. The formula is: value in kJ × 1,000 = value in J. Use the converter above to convert any value instantly.
1 J = 0.001 kJ. To convert back, divide the J value by 1,000 (or multiply by 0.001).
J = kJ × 1,000; conversely kJ = J ÷ 1,000. For example, 1 kJ × 1,000 = 1,000 J. The factor comes from the international definition of the units.
