How to Convert Megawatt-hours to Kilojoules

To convert a megawatt-hour measurement to a kilojoule measurement, multiply the energy by the conversion ratio.

Since one megawatt-hour is equal to 3,600,000 kilojoules, you can use this simple formula to convert:

kilojoules = megawatt-hours × 3,600,000

The energy in kilojoules is equal to the megawatt-hours multiplied by 3,600,000.

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

How Many Kilojoules Are in a Megawatt-hour?

There are 3,600,000 kilojoules in a megawatt-hour, which is why we use this value in the formula above.

1 MWh = 3,600,000 kJ

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

Megawatt-hours

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.[1]

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.
