What Is This Tool?
This tool converts power measurements from pound-foot per second, an Imperial mechanical power unit, to Btu (IT) per hour, a thermal power unit used for heat transfer rates.
How to Use This Tool?
-
Enter the value in pound-foot/second you want to convert.
-
Select pound-foot/second as the input unit.
-
Choose Btu (IT)/hour [Btu/h] as the output unit.
-
Review the converted value displayed in Btu (IT)/hour.
Key Features
-
Converts mechanical power in pound-foot/second to thermal power in Btu (IT)/hour [Btu/h].
-
Supports applications in mechanical engineering and HVAC systems.
-
Browser-based and easy to use for quick unit translation.
-
Handles conversions relevant for boilers, furnaces, and heat exchangers.
Examples
-
2 pound-foot/second equals 9.2524857368 Btu (IT)/hour.
-
0.5 pound-foot/second equals 2.3131214342 Btu (IT)/hour.
Common Use Cases
-
Calculating mechanical power from torque and rotational speed using Imperial units.
-
Rating HVAC equipment such as air-conditioners or furnaces for heat transfer capacity.
-
Estimating boiler or water heater heat output in thermal units.
-
Comparing mechanical power values to thermal power ratings.
-
Sizing heat exchangers by evaluating building heat loss or gain.
Tips & Best Practices
-
Ensure unit definitions align precisely with those used in your application.
-
Use this conversion to reconcile mechanical and thermal power values correctly.
-
Apply the tool in engineering and HVAC contexts where Imperial and thermal units mix.
Limitations
-
Conversion assumes exact unit definitions and does not include system inefficiencies.
-
Mechanical power and thermal power units measure different physical phenomena requiring context for equivalence.
-
The conversion factor is approximate due to rounding.
Frequently Asked Questions
