About both units

From

Mechanical Horsepower

Mechanical horsepower equals 745.7 watts — James Watt's 1782 definition based on horse labor. Used in US car engines, aircraft and some industrial equipment. US muscle cars quote hp; European cars usually kW or PS.

Real-world: Base Ford Mustang: ~310 hp. Lawn mower: 5 hp. Average car: 150–200 hp.

Volt-Ampere

The volt-ampere equals one watt for purely resistive loads, but differs from watts for inductive or capacitive AC loads. Used for transformer, UPS and generator sizing — which must handle apparent power, not just real power.

Real-world: Home UPS: 600–1500 VA. Transformer: kVA ratings. Motor power factor typically 0.8 — 1 kW motor = 1.25 kVA.
