How to convert kilojoules to joules

One kilojoules is equal to 1000 joules:

1kJ = 1000J

The energy E(J) in joules (J) is equal to the energy E(kJ) in kilojoules times 1000:

E(J) = E(kJ) × 1000

Example

Convert 3 kilojoules to joules.

The energy E in joules (J) is equal to 3 kilojoules times 1000:

E(J) = 3kJ × 1000 = 3000J
