Gigajoules to Kilowatt-hours Conversion
Enter the energy in gigajoules below to get the value converted to kilowatt-hours.
How to Convert Gigajoules to Kilowatt-hours
To convert a gigajoule measurement to a kilowatt-hour measurement, multiply the energy by the conversion ratio.
Since one gigajoule is equal to 277.777778 kilowatt-hours, you can use this simple formula to convert:
The energy in kilowatt-hours is equal to the gigajoules multiplied by 277.777778.
Gigajoules and kilowatt-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.
Kilowatt-hours
A kilowatt-hour is a measure of electrical energy equal to one kilowatt, or 1,000 watts, of power over a one hour period. Kilowatt-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.
Kilowatt-hours are usually abbreviated as kWh, although the formally adopted expression is kW·h. The abbreviation kW h is also sometimes used. For example, 1 kilowatt-hour can be written as 1 kWh, 1 kW·h, or 1 kW 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]
