What does one watt-second represent?

One watt-second equals the energy transferred by one watt of power sustained for one second, and is equivalent to one joule.

How is a kilowatt-second related to a kilojoule?

A kilowatt-second is equal to one kilojoule, representing the energy from one kilowatt applied for one second.

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

Use kilowatt-seconds for larger energy measurements or when working with power values near the kilowatt range for easier interpretation.
