How to Convert Watt-seconds to Kilojoules

Convert watt-seconds to kilojoules with this simple formula:

kilojoules = watt-seconds × 0.001

Converting a watt-second energy measurement to a kilojoule measurement involves multiplying the energy by the conversion ratio to find the result. One watt-second is equal to 0.001 kilojoules, so to convert simply multiply by 0.001.

For example:
5 Ws = (5 × 0.001) = 0.005 kJ

Watt-seconds and kilojoules are both units used to measure energy. Learn more about energy and find more energy measurement conversion calculators. Watt-seconds are an energy measurement and can be abbreviated as Ws, for example 1 Ws. Kilojoules are an SI derived unit of energy and can be abbreviated as kJ, for example 1 kJ.
