## How to Convert Kilojoules to Megawatt-Hours

To convert a measurement in kilojoules to a measurement in megawatt-hours, divide the energy by the following conversion ratio: 3,600,000 kilojoules/megawatt-hour.

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

megawatt-hours = kilojoules ÷ 3,600,000

The energy in megawatt-hours is equal to the energy in 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.

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

## What Is a Megawatt-Hour?

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]}
