## How to Convert Watt-hours to Kilojoules

To convert a watt-hour measurement to a kilojoule measurement, multiply the energy by the conversion ratio. One watt-hour is equal to 3.6 kilojoules, so use this simple formula to convert:

The energy in kilojoules is equal to the watt-hours multiplied by 3.6.

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

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

## Watt-hours

The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours can be abbreviated as *Wh*, for example 1 watt-hour can be written as 1 Wh.

## 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.
