What is a kilowatt used for?

A kilowatt measures power output or consumption in electrical appliances, motors, generators, and HVAC systems.

When should I use femtojoule per second as a unit?

Femtojoule per second is used to quantify extremely small energy transfer rates in nanoelectronics, quantum experiments, and experimental physics.

Why does converting kW to fJ/s result in such large numbers?

Because 1 kilowatt equals 10^18 femtojoules per second, conversions involve very large numerical values due to the scale difference.
