## How to Convert Gigajoules to Megawatt-hours

To convert a gigajoule measurement to a megawatt-hour measurement, multiply the energy by the conversion ratio. One gigajoule is equal to 0.277778 megawatt-hours, so use this simple formula to convert:

The energy in megawatt-hours is equal to the gigajoules multiplied by 0.277778.

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

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

## 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^{6}. Gigajoules can be abbreviated as *GJ*, for example 1 gigajoule can be written as 1 GJ.

## 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 can be abbreviated as *MWh*, for example 1 megawatt-hour can be written as 1 MWh.
