Kilowatt-hours to Gigajoules Conversion
Enter the energy in kilowatt-hours below to get the value converted to gigajoules.
How to Convert Kilowatt-hours to Gigajoules
To convert a kilowatt-hour measurement to a gigajoule measurement, multiply the energy by the conversion ratio.
Since one kilowatt-hour is equal to 0.0036 gigajoules, you can use this simple formula to convert:
The energy in gigajoules is equal to the kilowatt-hours multiplied by 0.0036.
Kilowatt-hours and gigajoules are both units used to measure energy. Keep reading to learn more about each unit of measure.
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]
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.
