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 10^{9}. 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 can be abbreviated as *kWh*, for example 1 kilowatt-hour can be written as 1 kWh.
