Gigajoules and megawatt-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.
Megawatt-hours
A megawatt-hour is a measure of electrical energy equal to one megawatt, or 1,000,000 watts, of power over a one hour period. Megawatt-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.
Megawatt-hours can be abbreviated as MWh, for example 1 megawatt-hour can be written as 1 MWh.
