Kilojoules to Megawatt-hours Conversion
Enter the energy in kilojoules below to get the value converted to megawatt-hours.
How to Convert Kilojoules to Megawatt-hours
To convert a kilojoule measurement to a megawatt-hour measurement, divide the energy by the conversion ratio. One megawatt-hour is equal to 3,600,000 kilojoules, so use this simple formula to convert:
The energy in megawatt-hours is equal to the kilojoules divided by 3,600,000.
Kilojoules and megawatt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.
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.
A megawatt-hour is a measure of electrical energy equal to one megawatt, or 1,000,000 watts, of power over a one hour period. Megawatt-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.
Megawatt-hours are usually abbreviated as MWh, although the formally adopted expression is MW·h. The abbreviation MW h is also sometimes used. For example, 1 megawatt-hour can be written as 1 MWh, 1 MW·h, or 1 MW 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.
