Conversion Definitions

The following is a list of definitions relating to conversions between kilojoules and joules.

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.

What is a joule (J)?

A joule is a unit of energy in the International System of Units (SI). The symbol for joule is J. There are 1,000 joules in a kilojoule.

Conversion Formula

Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.

The formula to convert from kJ to J is:

J = kJ x 1,000

Conversion Example

Next, let's look at an example showing the work and calculations that are involved in converting from kilojoules to joules (kJ to J).

Kilojoule to Joule Conversion Example

Task: Convert 8 kilojoules to joules (show work) Formula: kJ x 1,000 = J Calculations: 8 kJ x 1,000 = 8,000 J Result: 8 kJ is equal to 8,000 J
