What is a kilojoule (kJ)?

A kilojoule is a unit of energy in the International System of Units (SI).

The symbol for kilojoule is kJ.

There are 0.001 kilojoules in a joule.

Conversion Formula

If you want to convert Joule to kilojoule you need to divide the Joule value with 1000.

kJ = J ÷ 1,000

Joule to kilojoule Conversion Example (J to kJ)

If you take 200 joules and convert them to kilojoules you will get this:

Formula:

kJ = J ÷ 1,000

J to kJ Calculation:

200 J ÷ 1,000 = 0.2 kJ

Result:

200 J is equal to 0.2 kJ

Here are more details about energy. Energy variables are writen like this:

  • E(kJ) – Energy in kilojoules
  • E(J) – Energy in kilojoules

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

E(kJ) = E(J) / 1000
