What does kilovolt ampere (kV*A) measure?

Kilovolt ampere is a unit of apparent power in alternating-current electrical systems representing the product of RMS voltage and RMS current without considering the phase angle.

What is horsepower (550 ft·lbf/s) used for?

Horsepower at 550 foot‑pound‑force per second is an imperial power unit used for rating engines, small motors, and mechanical devices in contexts using imperial measurements.

Why does the conversion from kV*A to horsepower have limitations?

Because kilovolt ampere represents apparent electrical power without power factor, while horsepower measures mechanical output power, the conversion does not account for the electrical system's phase angle or efficiency differences.
