# Kilojoule Conversion Calculator

Enter a value in kilojoules below to convert to another unit of energy.

## What Is a Kilojoule?

A kilojoule is a unit used to measure energy.

The kilojoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "kilo" is the prefix for thousands, or 103. Kilojoules can be abbreviated as kJ; for example, 1 kilojoule can be written as 1 kJ.

## How Much Is a Kilojoule?

One kilojoule is equal to 1,000 joules, which is the energy equal to the force on an object of one newton at a distance of one meter.

## How to Convert Kilojoules

To convert kilojoules to another unit of energy, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for kilojoules in the conversion table below.

Then, multiply the energy measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

kilojoules × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
