About BTU per Hour and Kilowatt
1 BTU/h in this library is 0.29307107 W, so divide BTU/h by 3,412.14 to get kW. HVAC cooling tons are often 12,000 BTU/h ≈ 3.517 kW. This converts power rate, not stored energy in BTU.

Practical use cases for BTU per Hour to Kilowatt
HVAC equipment schedules
US catalogs in BTU/h must become kW for IEC electrical and European energy models. 12,000 BTU/h is 3.517 kW.
Heat-pump COP checks
Heating capacity in BTU/h divided by 3,412 gives kW of heat, which is compared to electrical kW input.
Boiler and furnace input
Input ratings on US gas appliances convert to kW for condensing-boiler comparisons sold in Europe.
Data-hall cooling
IT load in kW is matched to CRAC capacity still quoted in BTU/h or tons. Convert before a rack layout.
BTU per Hour to Kilowatt FAQs
Common questions about converting btu per hour to kilowatt.
How do you convert BTU per hour to kilowatts?
Multiply BTU/h by 0.000293071, or divide by 3,412.14. Example: 1,000 BTU/h = 0.29307 kW, 12,000 BTU/h = 3.51685 kW, 36,000 BTU/h = 10.5506 kW.
Is 12,000 BTU/h the same as a ton of refrigeration?
A refrigeration ton is defined as 12,000 BTU/h, which is 3.51685 kW on this page. Air-conditioning “ton” marketing can differ slightly; use the ton-of-refrigeration converter when the datasheet says RT.
Why is 3,412 BTU/h about 1 kW?
Because 1 kW = 1,000 W and 1 BTU/h = 0.293071 W, so 1,000 / 0.293071 ≈ 3,412 BTU/h per kilowatt. Heat-pump COP comparisons use this identity.
Does this convert BTU energy or BTU per hour?
BTU per hour only — a power unit. Total heat in BTU is energy and needs a time period. Do not use this page for therms or kWh without hours.
