## How to Convert Watt-seconds to Kilojoules

To convert a watt-second measurement to a kilojoule measurement, multiply the energy by the conversion ratio. One watt-second is equal to 0.001 kilojoules, so use this simple formula to convert:

The energy in kilojoules is equal to the watt-seconds multiplied by 0.001.

**For example,**here's how to convert 5 watt-seconds to kilojoules using the formula above.

Watt-seconds and kilojoules are both units used to measure energy. Keep reading to learn more about each unit of measure.

## Watt-seconds

The watt-second is a measure of electrical energy equal to one watt of power over a one second period. One watt-second is equal to 1/3,600 of a watt-hour or one joule.

Watt-seconds can be abbreviated as *Ws*, for example 1 watt-second can be written as 1 Ws.

## 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 10^{3}. Kilojoules can be abbreviated as *kJ*, for example 1 kilojoule can be written as 1 kJ.
