BTU/hr to kW

Change a power rating from BTU per hour into kilowatts in a single step. One BTU/hr is about 0.000293071070172222 kW, the rounded value of the factor 1055.05585262 / 3600000, which is what the tool multiplies by.

BTU per hour and the kilowatt

BTU per hour (BTU/hr) states power as the amount of heat energy that moves in one hour, counting the International Table (IT) BTU, which is defined as exactly 1055.05585262 joules. The kilowatt is a metric multiple of the watt, and one kilowatt is about 3412.142 BTU/hr.

Type any BTU/hr figure and press Convert to see the matching power in kilowatts. Copy puts the answer and its unit on your clipboard, and Clear resets the input and the result so you can try another number.

BTU/hr to kW formula

Because 1 BTU/hr is about 0.000293071070172222 kW, the power P in kilowatts is the BTU/hr figure multiplied by the fraction 1055.05585262 / 3600000, in short P(kW) ≈ P(BTU/hr) / 3412.14163312794. Read the other way, 1 kW ≈ 3412.14163312794 BTU/hr.

Example: 20000 BTU/hr is about 5.861 kW; carried further, 20000 BTU/hr ≈ 5.86142140344444 kW.
