About Converting Hectowatts to BTU per hour
Hectowatt and BTU per hour both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Hectowatt is 100 watt units, and power rate using BTU per hour.
Formula
btu per hour = hectowatts × 341.214163313
This factor comes from each unit's defined relationship to the category's base unit: 1 hectowatt equals 100 base units, and 1 btu per hour equals 0.293071070172 base units, so dividing one by the other gives the direct hectowatt-to-btu per hour factor of 341.214163313.
Simple example
1 hW × 341.2141633 = 341.2141633 BTU/h
1 hectowatt = 341.2141633 btu per hour.
Real-world example
100 hW × 341.2141633 = 34,121.41633 BTU/h
100 hectowatts = 34,121.41633 btu per hour.

Frequently asked questions
How many btu per hour are in 1 hectowatt?
1 hectowatt equals 341.2141633 btu per hour, using the exact defined conversion factor rather than an estimate.
How do I convert hectowatt to btu per hour?
Multiply the hectowatt value by 341.2141633. The converter above does this instantly to whatever precision you set.
How do I convert btu per hour back to hectowatt?
Use the reverse factor: 1 btu per hour equals 0.0029307107 hectowatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectowatt?
Hectowatt (hW) is a unit of engineering.
What is a btu per hour?
BTU per hour (BTU/h) is a unit of engineering.
Is the hectowatt to btu per hour conversion exact?
Yes. Both hectowatt and btu per hour are defined by fixed standards rather than physical artifacts, so the factor of 341.2141633 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
