How to Convert Joules to Kilojoules

A joule is equivalent to one thousandth of a kilojoule, represented as:

1J = 0.001kJ

To convert energy from joules E(J) to kilojoules E(kJ), simply divide the energy in joules by 1000:

E(kJ) = E(J) / 1000

Example

Let’s say we have a system that has an energy value of 5000 joules. To convert this to kilojoules, we divide the energy value by 1000 (since there are 1000 joules in 1 kilojoule).

5000 joules ÷ 1000 = 5 kilojoules

Therefore, 5000 joules is equal to 5 kilojoules.
