Gigajoules and watt-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.

## Watt-hours

The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours can be abbreviated as *Wh*, for example 1 watt-hour can be written as 1 Wh.
