1 BTU/h = 0.00029307107 kW
Examples
- One ton of refrigeration: 12,000 BTU/h ÷ 3,412.14163 = 3.51685284 kW
- 5,000 BTU/h ÷ 3,412.14163 = 1.46535535 kW
Good to know
One kilowatt is about 3412 BTU per hour. A 12,000 BTU/h air conditioner therefore has a cooling capacity of about 3.5 kW, which is not the same as its electrical power draw.
This uses the International Table BTU, 1055.05585262 J. Air conditioner and heater ratings quoted simply in "BTU" mean BTU per hour.
