## How to Convert Kilojoules to Watt-Seconds

To convert a measurement in kilojoules to a measurement in watt-seconds, multiply the energy by the following conversion ratio: 1,000 watt-seconds/kilojoule.

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

watt-seconds = kilojoules × 1,000

The energy in watt-seconds is equal to the energy in kilojoules multiplied by 1,000.

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

### How Many Watt-Seconds Are in a Kilojoule?

There are **1,000** watt-seconds in a kilojoule, which is why we use this value in the formula above.

1 kJ = 1,000 Ws

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

## What Is a Kilojoule?

One kilojoule is equal to 1,000 joules, which is the energy equal to the force on an object of one newton at a distance of one meter.

The kilojoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "kilo" is the prefix for thousands, or 10^{3}. Kilojoules can be abbreviated as *kJ*; for example, 1 kilojoule can be written as 1 kJ.

## 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]}
