About Kilowatt To BTU Per Hour Calculator

Converting Kilowatts to BTU per hour is one multiplication: a single kW is 3412.14163313 BTU/h, so the amount is scaled by that factor. Reversing the direction divides by the same factor. The factor is an exact definition rather than a rounded figure, so the result stays precise at any magnitude. 1 kW is about 3,412 BTU/h. A '12,000 BTU' air conditioner is one ton of cooling, roughly 3.52 kW.
