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:

kilowatt-hours = kilojoules ÷ 3,600

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.
5,000 kJ = (5,000 ÷ 3,600) = 1.388889 kWh

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 103. 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]
