About both units

From

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.

To

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.

Tips & common mistakes

Quick tips

  • 1 BTU/h = 0.293 W; 3412 BTU/h = 1 kW.
  • 12,000 BTU/h = 1 ton of refrigeration.
  • Tons of AC rating: divide BTU/h by 12,000.

Avoid these

  • Confusing BTU (energy) with BTU/h (power) — same abbreviation in ads.
  • Mixing tons of AC and tons of weight — different concepts.
  • Using BTU/h for non-HVAC contexts.

Frequently asked questions

How many volt-amperes in a btu per hour?
One btu per hour equals 0.2931 volt-amperes.
How do I convert BTU per hour to volt-amperes?
