## How to Convert Megawatt-hours to Gigajoules

To convert a megawatt-hour measurement to a gigajoule measurement, multiply the energy by the conversion ratio. One megawatt-hour is equal to 3.6 gigajoules, so use this simple formula to convert:

The energy in gigajoules is equal to the megawatt-hours multiplied by 3.6.

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

Megawatt-hours and gigajoules 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]}

## Gigajoules

One gigajoule is equal to 1,000,000,000 joules, which are the energy equal to the force on an object of one newton at a distance of one meter.

The gigajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "giga" is the prefix for 10^{9}. Gigajoules can be abbreviated as *GJ*; for example, 1 gigajoule can be written as 1 GJ.
