Kilowatts to BTU/hr

Enter a power value in kilowatts and press Convert to get the equivalent in BTU per hour. The tool multiplies by 3600000 / 1055.05585262, whose rounded value is about 3412.142 BTU/hr per kilowatt.

Kilowatts and BTU per hour

Kilowatts and BTU per hour are both units of power, so a rating given in one can be restated in the other. The BTU used here is the International Table (IT) BTU, defined as exactly 1055.05585262 joules, and a kilowatt hour is exactly 3600000 joules; the ratio of those two exact figures gives about 3412.142 BTU/hr per kW. This tool takes the number you enter in kW and returns the same power expressed in BTU per hour.

Because the rate is fixed, larger ratings scale in proportion: each additional kilowatt adds about 3412.142 BTU/hr to the result.

kW to BTU/hr formula

The power P in BTU per hour is the power P in kilowatts multiplied by about 3412.142: P(BTU/hr) ≈ 3412.142 × P(kW).

For example, converting 5 kW gives P(BTU/hr) ≈ 3412.142 × 5 ≈ 17060.71 BTU/hr. To work backwards, divide a BTU/hr figure by about 3412.142, or multiply it by about 0.000293071, to get kilowatts.
