Are kilowatt and kilojoule per second different units?

No, both units measure power and are equivalent in magnitude, representing the rate of energy transfer per second.

Why would I convert kilowatts to kilojoules per second?

Converting helps express power consistently in contexts where energy transfer per second measured in joules is preferred, such as thermal or mechanical systems.

Does this conversion consider power efficiency?

No, the conversion only reflects equivalent unit magnitudes and does not account for efficiency or power factor in actual systems.
