How to Convert Kilowatt-hours to Kilojoules

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

kilojoules = kilowatt-hours × 3,600

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

For example, here's how to convert 5 kilowatt-hours to kilojoules using the formula above.
5 kWh = (5 × 3,600) = 18,000 kJ

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

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 can be abbreviated as kWh, for example 1 kilowatt-hour can be written as 1 kWh.

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.
