What Is This Tool?
This converter transforms power measurements from pound-foot per hour, a unit of mechanical work rate in imperial units, into calorie (th)/second, a unit of thermal power based on energy transfer per second. It helps translate low continuous mechanical outputs into thermal energy flow rates.
How to Use This Tool?
-
Enter the power value in pound-foot/hour
-
Select pound-foot/hour as the input unit and calorie (th)/second as the output unit
-
Execute the conversion to see the equivalent thermal power
-
Review the results to understand mechanical to thermal power translation
Key Features
-
Converts power from pound-foot/hour to calorie (th)/second accurately
-
Supports legacy imperial mechanical power units
-
Enables comparison between mechanical work rates and thermal energy rates
-
Browser-based and easy to use with clear conversion steps
-
Fits applications in mechanical engineering, calorimetry, and thermal systems
Examples
-
Convert 10 pound-foot/hour to calorie (th)/second: 10 × 0.0000900134 = 0.000900134 cal(th)/s
-
Convert 100 pound-foot/hour to calorie (th)/second: 100 × 0.0000900134 = 0.00900134 cal(th)/s
Common Use Cases
-
Expressing very low continuous mechanical output in legacy imperial units
-
Documenting power specifications of vintage mechanical equipment
-
Estimating hand-crank or slow winch work rates for equipment conversions
-
Reporting heat flow in calorimetry laboratories
-
Specifying power ratings of small heating elements in older engineering contexts
-
Converting legacy thermal power data for HVAC and process engineering
Tips & Best Practices
-
Ensure correct time units are considered when comparing results since pound-foot/hour and calorie (th)/second use different time bases
-
Use this tool primarily for low power values due to the nature of pound-foot/hour
-
Apply conversions when working with historical or legacy data to maintain consistency
-
Verify that your engineering context supports the use of calories as a thermal power unit
Limitations
-
Pound-foot/hour applies to very low mechanical power only
-
Conversion involves different time units, so careful interpretation is needed
-
Not suitable for high-power industrial applications
-
Limited to specialized or legacy data contexts rather than modern widespread use
Frequently Asked Questions
-
What does pound-foot per hour measure?
-
Pound-foot per hour quantifies mechanical power as the rate of work done in imperial units, specifically one foot-pound of force applied per hour.
-
Why convert pound-foot/hour to calorie (th)/second?
-
This conversion allows translation of mechanical power rates in legacy imperial units into thermal power units, facilitating thermal energy analyses such as calorimetry.
-
Is this conversion suitable for high-power calculations?
-
No, pound-foot/hour is a very low mechanical power unit, so this converter is intended mainly for low-magnitude, specialized or legacy power measurements.
Key Terminology
-
Pound-foot per hour [lbf*ft/h]
-
An imperial power unit representing one foot-pound of mechanical work performed every hour, commonly used for very low power rates.
-
Calorie (th)/second
-
A unit of power defined as the transfer of one thermochemical calorie of energy per second, where one calorie (thermochemical) equals 4.184 joules.
