How to convert
To convert kJ to MJ, multiply: MJ = kJ × 0.001
To convert MJ to kJ, divide: kJ = MJ ÷ 0.001 (equivalently × 1,000).
Example: 3,600 kJ × 0.001 = 3.6 MJ. The factor is derived from the international definition of each unit; results are shown to 4 significant figures.
Frequently asked questions
