Conversion formula

Forward
BTU per hour = volt-amperes × 3.41214
Reverse
volt-amperes = BTU per hour × 0.2931

Example: 10 VA × 3.41214 = 34.1214 BTU/h.

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.

BTU per Hour

BTU/h

BTU per hour equals 0.293 watts. It is the standard power unit for US HVAC — air conditioners, heaters and boilers. A 24,000 BTU/h AC provides 7 kW of cooling.

Real-world: Small window AC: 5000 BTU/h. Central AC: 24,000 BTU/h. Home furnace: 80,000 BTU/h.

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.
