0.001341

Conversion formula

Forward
mechanical horsepower = volt-amperes × 0.001341
Reverse
volt-amperes = mechanical horsepower × 745.7

Example: 10 VA × 0.001341 = 0.01341 hp.

About both units

From

Volt-Ampere

VA

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.

Mechanical Horsepower

hp

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.

Tips & common mistakes

Quick tips

  • VA = V × A (RMS).
  • For purely resistive loads, VA = W.
  • For motors, computers: VA > W (power factor < 1).

Avoid these

  • Treating VA and W as identical — only true for resistive loads.
  • Buying UPS by W when VA rating is required.
  • Ignoring power factor in transformer sizing.

Frequently asked questions

How many mechanical horsepower in a volt-ampere?
One volt-ampere equals 0.001341 mechanical horsepower.
