How to Convert Kilojoules to Watt-seconds

To convert a kilojoule measurement to a watt-second measurement, multiply the energy by the conversion ratio. One kilojoule is equal to 1,000 watt-seconds, so use this simple formula to convert:

watt-seconds = kilojoules × 1,000

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

For example, here's how to convert 5 kilojoules to watt-seconds using the formula above.
5 kJ = (5 × 1,000) = 5,000 Ws

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

Kilojoules

One kilojoule is equal to 1,000 joules, which are 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 103. Kilojoules can be abbreviated as kJ, for example 1 kilojoule can be written as 1 kJ.

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.
