What Is This Tool?
This unit converter allows you to transform measurements of power from foot pound-force per hour, a legacy imperial unit representing mechanical work or energy transfer, into kilocalorie (thermochemical) per hour, a unit that quantifies heat flow rate. It helps bridge units commonly used in mechanical and thermal energy contexts.
How to Use This Tool?
-

Examples
-
100 foot pound-force/hour = 0.03240483 kilocalorie (th)/hour
-
500 foot pound-force/hour = 0.16202415 kilocalorie (th)/hour
Common Use Cases
-
Expressing small mechanical power or work rates in legacy imperial equipment documentation
-
Converting historical mechanical power specifications into comparable thermal power units
-
Rating heat output and thermal gains or losses in HVAC and appliance manufacturing
-
Supporting energy throughput analysis where foot pound-force/hour units appear alongside thermal energy metrics
-
Evaluating mechanical and thermal equipment performance using compatible units
Tips & Best Practices
-
Ensure correct unit selection to avoid conversion errors between mechanical and thermal power units
-
Use this tool for interpreting and comparing legacy mechanical power data in thermal terms
-
Refer to the provided conversion formula for manual verification where needed
-
Keep in mind that foot pound-force/hour is a very small power unit requiring precise handling
-
Confirm that kilocalorie (th)/hour applies only to thermochemical calorie definitions
Limitations
-
Foot pound-force/hour is a non-SI unit with very small magnitude, requiring careful conversion
-
Kilocalorie (th)/hour references thermochemical calories and is not suitable for other calorie definitions
-
Conversion accuracy depends on strict adherence to unit definitions, especially for historical data
-
This tool does not account for variations in legacy unit usage or non-standard definitions
Frequently Asked Questions
-
What does foot pound-force per hour measure?
-
Foot pound-force per hour is a unit of power representing the rate of mechanical work or energy transfer equal to one foot-pound-force done every hour.
-
Why convert foot pound-force/hour to kilocalorie (th)/hour?
-
Converting to kilocalorie (th)/hour helps translate mechanical power from old imperial units into thermal power measures relevant for heating and cooling applications.
-
Is kilocalorie (th)/hour the same as other calorie-based units?
-
No, kilocalorie (th)/hour specifically refers to thermochemical calories per hour and may differ from other calorie unit definitions.
