## How to Convert Kilojoules to Kilowatt-hours

To convert a kilojoule measurement to a kilowatt-hour measurement, divide the energy by the conversion ratio. One kilowatt-hour is equal to 3,600 kilojoules, so use this simple formula to convert:

The energy in kilowatt-hours is equal to the kilojoules divided by 3,600.

**For example,**here's how to convert 5,000 kilojoules to kilowatt-hours using the formula above.

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

## 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.

## Kilowatt-hours

A kilowatt-hour is a measure of electrical energy equal to one kilowatt, or 1,000 watts, of power over a one hour period. Kilowatt-hours are a measure of electrical work performed over a period of time, and are often used as a way of measuring energy usage by electric companies.

Kilowatt-hours are usually abbreviated as *kWh*, although the formally adopted expression is *kW·h*. The abbreviation *kW h* is also sometimes used. For example, 1 kilowatt-hour can be written as 1 kWh, 1 kW·h, or 1 kW h.

In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.^{[1]}
