Enter the energy in gigajoules below to get the value converted to watt-hours.
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:
The energy in watt-hours is equal to the gigajoules multiplied by 277,777.777778.
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 are usually abbreviated as Wh, although the formally adopted expression is W·h. The abbreviation W h is also sometimes used. For example, 1 watt-hour can be written as 1 Wh, 1 W·h, or 1 W 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]
