How to convert Millijoules to Joules
Multiply the millijoules value by 0.001: 1 mJ = 0.001 J. Going the other way, 1 J = 1,000 mJ, so divide by 0.001 or use the Joules to Millijoules converter.
About these units
Joules (J)
The joule is the SI unit of energy: the work done by a force of one newton over one meter. Lifting a small apple one meter takes about one joule.
