BTU to kW Converter
Convert BTU per hour (BTU/h) to kilowatts (kW) instantly. Type a value — the result updates as you type, and the swap button converts the other way.
BTU/h to kW formula
kW = BTU/h × 0.00029307107
1 BTU per hour = 0.000293 kilowatts · 1 kilowatt = 3412.14 BTU per hour
To convert BTU per hour to kilowatts, multiply the value by 0.00029307107. For example, 12000 BTU/h:
kW = 12000 × 0.00029307107kW = 3.516853
So 12000 BTU/h = 3.52 kW.
Mental math shortcut
Quick mental estimate: divide by 3,400. For 12000 BTU/h that gives about 3.53 kW — within 1% of the exact answer. Use the exact formula when precision matters.
