Kilowatt-hours to Kilojoules Conversion
Enter the energy in kilowatt-hours below to get the value converted to kilojoules.
How to Convert Kilowatt-hours to Kilojoules
To convert a kilowatt-hour measurement to a kilojoule measurement, multiply the energy by the conversion ratio.
Since one kilowatt-hour is equal to 3,600 kilojoules, you can use this simple formula to convert:
The energy in kilojoules is equal to the kilowatt-hours multiplied by 3,600.
How Many Kilojoules Are in a Kilowatt-hour?
There are 3,600 kilojoules in a kilowatt-hour, which is why we use this value in the formula above.
1 kWh = 3,600 kJ
Kilowatt-hours and kilojoules are both units used to measure energy. Keep reading to learn more about each unit of measure.
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.
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.
