Key Stage 4
Meaning
Millijoules (mJ) are a unit of energy 1,000 times smaller than the SI Unit of the Joules.
About Millijoules
- Millijoules are shortened to mJ with a lower case m and an upper case J.
- Milli means one thousandth so there are 1,000 millijoules in a Joule.
Converting to Millijoules
| Unit | To convert | Millijoules |
| 1 megajoule (1MJ) | Convert to millijoules x109 | 1x109mJ |
| 1 kilojoule (1kJ) | Convert to millijoules x106 | 1x106mJ |
| 1 Joule (1J) | Convert to millijoules x103 | 1x103mJ |
| 1 millijoule 1(mJ) | Convert to millijoules x1 | 1mJ |
| 1 microjoule 1(µJ) | Convert to millijoules x10-3 | 1x10-3mJ |
| 1 nanojoule 1(nJ) | Convert to millijoules x10-6 | 1x10-6mJ |
