## How to Convert Watt-Seconds to Gigajoules

To convert a measurement in watt-seconds to a measurement in gigajoules, divide the energy by the following conversion ratio: 1,000,000,000 watt-seconds/gigajoule.

Since one gigajoule is equal to 1,000,000,000 watt-seconds, you can use this simple formula to convert:

gigajoules = watt-seconds ÷ 1,000,000,000

The energy in gigajoules is equal to the energy in watt-seconds divided by 1,000,000,000.

**For example,**here's how to convert 500,000,000 watt-seconds to gigajoules using the formula above.

Watt-seconds and gigajoules are both units used to measure energy. Keep reading to learn more about each unit of measure.

## What Is a Watt-Second?

The watt-second is a measure of electrical energy equal to one watt of power over a one second period. One watt-second is equal to 1/3,600 of a watt-hour or one joule.

Watt-seconds are usually abbreviated as *Ws*, although the formally adopted expression is *W·s*. The abbreviation *W s* is also sometimes used. For example, 1 watt-second can be written as 1 Ws, 1 W·s, or 1 W s.

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]}

## What Is a Gigajoule?

One gigajoule is equal to 1,000,000,000 joules, which is 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 billions, or 10^{9}. Gigajoules can be abbreviated as *GJ*; for example, 1 gigajoule can be written as 1 GJ.
