Convert BTU per hour to Kilowatts

1 BTU per hour is 0.000293 kW. One BTU per hour is exactly 0.000293071070172 kilowatts.

One BTU per hour is 2.9307 × 10^-4 kilowatts. To convert BTU per hour to kilowatts, multiply by 2.9307 × 10^-4; to go the other way, divide by 2.9307 × 10^-4 or multiply by 3412.1416. The factor is exact rather than rounded: it follows from NIST Special Publication 811. The rate US heating and air conditioning is sold in.

How do you convert BTU per hour to kilowatts?

  1. 1.Take the measurement in BTU per hour.
  2. 2.Multiply by 2.9307 × 10^-4 — that is how many kilowatts fit in one BTU per hour.
  3. 3.To go back the other way, divide by 2.9307 × 10^-4, or multiply by 3412.1416.

Worked example: 25 BTU per hour to kilowatts

Formula
BTU/h × 2.9307 × 10^-4 = kW
Arithmetic
25 × 2.9307 × 10^-4 = 0.007327 kW
Answer
25 BTU/h = 0.007327 kW

The factor is rounded for display; the figure above is computed from the full value.

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.

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.

How many kilowatts are in a BTU per hour?

One BTU per hour is 2.9307 × 10^-4 kilowatts. Going the other way, one kilowatt is 3412.1416 BTU per hour. 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.
