About This Conversion
BTU to kilowatt-hours divides by 3,412.14. The British thermal unit is the heating and cooling industry standard in the US, while electricity and most of the rest of the world work in kilowatt-hours, so the conversion is the one that lets two appliances be compared.
Air-conditioner ratings are the usual case, with a catch: a "12,000 BTU" unit means 12,000 BTU per hour, a rate, not an amount. That rate is 3.517 kW of cooling, and how much electricity it draws depends on its efficiency rating, not on the BTU figure alone.
