## How to Convert Kilojoules to Megawatt-hours

To convert a kilojoule measurement to a megawatt-hour measurement, divide 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:

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

**For example,**here's how to convert 5,000,000 kilojoules to megawatt-hours using the formula above.

Kilojoules and megawatt-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 10^{3}. Kilojoules can be abbreviated as *kJ*; for example, 1 kilojoule can be written as 1 kJ.

## 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]}
