## How to convert joules to watt seconds (J to Ws)

The formula for converting joules to watt seconds is: Ws = J × 1. To calculate the joule value in watt seconds first substitute the joule value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 joule in watt seconds we follow these steps:

Ws = J × 1

Ws = 1 × 1

Ws = 1

In other words, 1 joule is equal to 1 watt second.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 9 joules to watt seconds is:

- Understand the conversion formula: Ws = J × 1
- Substitute the required value. In this case we substitute 9 for J so the formula becomes: Ws = 9 × 1
- Calculate the result using the provided values. In our example the result is: 9 × 1 = 9 Ws

In summary, 9 joules is equal to 9 watt seconds.

## Converting watt seconds to joules

In order to convert the other way around i.e. watt seconds to joules, you would use the following formula: J = Ws × 1. To convert watt seconds to joules first substitute the watt second value into the above formula, and then execute the calculation. If we wanted to calculate 1 watt second in joules we follow these steps:

J = Ws × 1

J = 1 × 1

J = 1

Or in other words, 1 watt second is equal to 1 joule.
