What is one kilowatt-second equal to in kilojoules?

One kilowatt-second is equal to one kilojoule, since 1 kW*s = 1 kJ.

When should I use kilowatt-seconds instead of kilowatt-hours?

Kilowatt-seconds are suitable for short-duration energy calculations, especially pulses lasting around one second, whereas kilowatt-hours are used for longer energy intervals.

Can this converter handle fluctuating power outputs?

The conversion assumes constant power output during one second; rapidly changing power requires more precise integration methods.
