About Converting BTU per hour to Kilowatts
BTU per hour and Kilowatt both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Specifically: Power rate using BTU per hour, and kilowatt is 1000 watt units.
Formula
kilowatts = btu per hour × 0.000293071070172
This factor comes from each unit's defined relationship to the category's base unit: 1 btu per hour equals 0.293071070172 base units, and 1 kilowatt equals 1000 base units, so dividing one by the other gives the direct btu per hour-to-kilowatt factor of 0.000293071070172.
Simple example
1 BTU/h × 0.0002930710702 = 0.0002930711 kW
1 btu per hour = 0.0002930711 kilowatts.
Real-world example
100 BTU/h × 0.0002930710702 = 0.029307107 kW
100 btu per hour = 0.029307107 kilowatts.
Conversion table
| BTU per hour (BTU/h) | Kilowatt (kW) |
|---|---|
| 1 BTU/h | 0.0002930711 kW |
| 10 BTU/h | 0.0029307107 kW |
| 100 BTU/h | 0.029307107 kW |
| 500 BTU/h | 0.1465355351 kW |
| 1,000 BTU/h | 0.2930710702 kW |
| 5,000 BTU/h | 1.465355351 kW |
Reverse conversion: Kilowatt to BTU per hour
0.0002930711 kW × 3412.141633 = 1.000000102 BTU/h
0.0002930711 kilowatts = 1.000000102 btu per hour.
btu per hour = kilowatts × 3412.14163313

Understanding the Kilowatt
Kilowatt (kW) measures power. A kilowatt is 1,000 watts. It is classified as a SI derived (metric prefix) unit.
Where it's used: Standard power unit worldwide for larger appliances, vehicles, and electrical systems
Uses of the Kilowatt today
- Electric vehicle motor power ratings (alongside horsepower)
- Household electrical system and generator capacity
- Industrial motor and equipment power ratings
History of the Kilowatt
The kilowatt follows directly from the watt via the standard SI 'kilo-' prefix, becoming especially prominent with the growth of electrical power generation and distribution in the late 19th and 20th centuries.
Historical origin. Kilowatt was not the invention of a single named person; it developed through the process described above.
Kilowatt — sources
- BIPM SI Brochure — SI prefixes — Defines 'kilo-' as the prefix for 10³.

How many kilowatts are in 1 btu per hour?
1 btu per hour equals 0.0002930711 kilowatts, using the exact defined conversion factor rather than an estimate.
How do I convert btu per hour to kilowatt?
Multiply the btu per hour value by 0.0002930710702. The converter above does this instantly to whatever precision you set.
How do I convert kilowatt back to btu per hour?
Use the reverse factor: 1 kilowatt equals 3,412.141633 btu per hour. You can also use the swap control in the converter above to flip the direction instantly.
What is a btu per hour?
BTU per hour (BTU/h) is a unit of power.
What is a kilowatt?
Kilowatt (kW) measures power. A kilowatt is 1,000 watts. It is classified as a SI derived (metric prefix) unit.
Is the btu per hour to kilowatt conversion exact?
Yes. Both btu per hour and kilowatt are defined by fixed standards rather than physical artifacts, so the factor of 0.0002930710702 used above is exact to as many digits as you choose to display.
