How to Convert Gigajoules to Watt-hours

To convert a gigajoule measurement to a watt-hour measurement, multiply the energy by the conversion ratio. One gigajoule is equal to 277,777.777778 watt-hours, so use this simple formula to convert:

watt-hours = gigajoules × 277,777.777778

The energy in watt-hours is equal to the gigajoules multiplied by 277,777.777778.

For example, here's how to convert 5 gigajoules to watt-hours using the formula above.
5 GJ = (5 × 277,777.777778) = 1,388,888.888889 Wh

Gigajoules and watt-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 109. Gigajoules can be abbreviated as GJ, for example 1 gigajoule can be written as 1 GJ.

Watt-hours

The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours can be abbreviated as Wh, for example 1 watt-hour can be written as 1 Wh.
