Convert Kilowatts to BTU per hour
1 kilowatt is 3,412.141633 BTU/h. One kilowatt is exactly 3412.14163313 BTU per hour.
One kilowatt is 3412.1416 BTU per hour. To convert kilowatts to BTU per hour, multiply by 3412.1416; to go the other way, divide by 3412.1416 or multiply by 2.9307 × 10^-4. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A thousand watts.

How do you convert kilowatts to BTU per hour?
- 1.Take the measurement in kilowatts.
- 2.Multiply by 3412.1416 — that is how many BTU per hour fit in one kilowatt.
- 3.To go back the other way, divide by 3412.1416, or multiply by 2.9307 × 10^-4.
Worked example: 25 kilowatts to BTU per hour
- Formula
- kW × 3412.1416 = BTU/h
- Arithmetic
- 25 × 3412.1416 = 85,303.540828 BTU/h
- Answer
- 25 kW = 85,303.540828 BTU/h
The factor is rounded for display; the figure above is computed from the full value.

What is a kilowatt?
A thousand watts. Electric motors, kettles and EV chargers are rated here, and a kilowatt is close to 1.34 horsepower.
What is a BTU per hour?
The rate US heating and air conditioning is sold in. A 12,000 BTU/h unit is one "ton" of cooling and about 3.5 kilowatts of heat moved.
How many BTU per hour are in a kilowatt?
One kilowatt is 3412.1416 BTU per hour. Going the other way, one BTU per hour is 2.9307 × 10^-4 kilowatts. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
