To convert a measurement in kilojoules to a measurement in kilowatt-hours, divide the energy by the following conversion ratio: 3,600 kilojoules/kilowatt-hour.

Since one kilowatt-hour is equal to 3,600 kilojoules, you can use this simple formula to convert:

kilowatt-hours = kilojoules ÷ 3,600

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

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

What Is a Kilojoule?

One kilojoule is equal to 1,000 joules, which is 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 thousands, or 103. Kilojoules can be abbreviated as kJ; for example, 1 kilojoule can be written as 1 kJ.

What Is a Kilowatt-Hour?

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]
