Key Stage 4
Meaning
Kilojoules (kJ) are a unit of energy 1,000 times larger than the SI Unit of the Joule.
About Kilojoules
- Kilojoules are shortened to kJ with a lower case k and an upper case J.
- Kilo means one thousand so there are 1,000 Joules in a kilojoule.
Converting to Kilojoules
| Unit | To convert | Kilojoules |
| 1 megajoule (1MJ) | Convert to kilojoules x103 | 1x103kJ |
| 1 kilojoule (1kJ) | Convert to kilojoules x1 | 1kJ |
| 1 Joule (1J) | Convert to kilojoules x10-3 | 1x10-3kJ |
| 1 millijoule 1(mJ) | Convert to kilojoules x10-6 | 1x10-6kJ |
| 1 microjoule 1(µJ) | Convert to kilojoules x10-9 | 1x10-9kJ |
| 1 nanojoule 1(nJ) | Convert to kilojoules x10-12 | 1x10-12kJ |
