What Is This Tool?
This converter allows you to change power values from Btu (th)/hour, a unit commonly used in heating and cooling systems, into kilowatts, the standard SI unit of power. It helps simplify comparing thermal power to electrical power measurements.
How to Use This Tool?
-
Enter the power value expressed in Btu (th)/hour.
-
Choose Btu (th)/hour as the input unit and kilowatt as the output unit.
-
Click convert to obtain the equivalent power in kilowatts.
-
Use the result to compare or specify power in SI units.

Be mindful of the unit context when applying conversion results in engineering projects.
Limitations
-
Conversion applies only to thermochemical BTU per hour measurements.
-
Minor differences in BTU definitions might cause slight variations.
-
Rounding and approximate constants affect conversion precision.
-
Btu (th)/hour is less familiar outside HVAC and thermal engineering fields.
Frequently Asked Questions
-
What does Btu (th)/hour measure?
-
Btu (th)/hour measures power as the rate of heat transfer in thermochemical British thermal units per hour, commonly used in HVAC applications.
-
Why convert Btu (th)/hour to kilowatts?
-
Converting to kilowatts standardizes power measurements, making it easier to compare heating or cooling power with electrical power ratings.
-
Can I use this conversion for all types of BTU units?
-
This conversion specifically applies to thermochemical BTU per hour; other BTU variants may not convert accurately using this rate.
Key Terminology
-
Btu (th)/hour
-
A unit of power defined as one thermochemical British thermal unit transferred per hour, used to quantify heating or cooling rates.
-
kilowatt (kW)
-
An SI derived unit of power equal to 1,000 watts, representing the rate of energy transfer or conversion.
