# Kilojoules to Joules Conversion

Enter the energy in kilojoules below to get the value converted to joules.

Results in Joules: 1 kJ = 1,000 J

## How to Convert Kilojoules to Joules

To convert a kilojoule measurement to a joule measurement, multiply the energy by the conversion ratio. One kilojoule is equal to 1,000 joules, so use this simple formula to convert:

joules = kilojoules × 1,000

The energy in joules is equal to the kilojoules multiplied by 1,000.

For example, here's how to convert 5 kilojoules to joules using the formula above.
5 kJ = (5 × 1,000) = 5,000 J

## Kilojoules

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

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 103. Kilojoules can be abbreviated as kJ; for example, 1 kilojoule can be written as 1 kJ.

## Joules

The joule is the energy equal to the force on an object of one newton at a distance of one meter. One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as J; for example, 1 joule can be written as 1 J.
