Watt-hours to Gigajoules Conversion
Enter the energy in watt-hours below to get the value converted to gigajoules.
How to Convert Watt-hours to Gigajoules
To convert a watt-hour measurement to a gigajoule measurement, multiply the energy by the conversion ratio.
Since one watt-hour is equal to 3.6E-6 gigajoules, you can use this simple formula to convert:
The energy in gigajoules is equal to the watt-hours multiplied by 3.6E-6.
Watt-hours and gigajoules are both units used to measure energy. Keep reading to learn more about each unit of measure.
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.
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.
