## How to Convert Joules to Watt-seconds

To convert a joule measurement to a watt-second measurement, divide the energy by the conversion ratio. One watt-second is equal to 1 joule, so use this simple formula to convert:

The energy in watt-seconds is equal to the joules divided by 1.

**For example,**here's how to convert 5 joules to watt-seconds using the formula above.

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

## Joules

The joule is the energy equal to the force on an object of one newton at a distance of one meter.^{[1]} One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as *J*, for example 1 joule can be written as 1 J.

## Watt-seconds

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 can be abbreviated as *Ws*, for example 1 watt-second can be written as 1 Ws.
