What Is This Tool?
This tool converts power values from pound-foot per hour (lbf*ft/h), a unit of very low mechanical power in imperial units, to Btu (IT) per second, a unit of heat transfer power used in heating and energy calculations.
How to Use This Tool?
-
Enter the power value in pound-foot/hour (lbf*ft/h) you want to convert.
-
Select pound-foot/hour as the input unit and Btu (IT)/second as the output unit.
-
Click the convert button to see the equivalent power in Btu (IT)/second.
-
Refer to examples to understand typical conversion results.

-
5000 lbf*ft/h is about 0.0017848159 Btu/s
Common Use Cases
-
Expressing very low continuous mechanical output in legacy imperial units
-
Documenting historical or vintage equipment mechanical power data
-
Converting old imperial mechanical power ratings to thermal power units used in HVAC
-
Sizing and rating boilers, furnaces, and industrial heaters in BTU units
-
Performing energy-balance calculations in engineering involving BTU measurements
Tips & Best Practices
-
Ensure accurate input of mechanical power values in pound-foot/hour for reliable conversion
-
Use this tool primarily for low-power or legacy equipment measurements
-
Cross-check converted values when applying to modern HVAC or heating system specifications
-
Understand the small scale of pound-foot/hour compared to Btu/second to interpret results correctly
Limitations
-
Pound-foot/hour is suitable only for very low mechanical power levels, not high-power applications
-
Conversion yields very small values which might need precise instrumentation or calculations
-
Mostly applicable to niche legacy equipment or detailed low-power mechanical assessments
Frequently Asked Questions
-
What does pound-foot/hour measure?
-
It measures mechanical power as the rate of work done in foot-pounds per hour, representing very low power in imperial units.
-
Why convert pound-foot/hour to Btu (IT)/second?
-
Converting enables bridging mechanical power in legacy units to thermal power units commonly used in heating and energy transfer fields.
-
Is this conversion useful for high-power industrial systems?
-
No, pound-foot/hour is primarily for low-power situations, so conversion to Btu/second is generally for small-scale or historical applications.
Key Terminology
-
Pound-foot per hour (lbf·ft/h)
-
An imperial unit of mechanical power representing foot-pound of work done per hour, indicating very low mechanical power.
-
Btu (IT)/second
-
A unit of power indicating the transfer of one British thermal unit per second, commonly used to specify heat transfer and energy conversion.
