What Is This Tool?
This tool converts power values from foot pound-force per hour to Btu (th) per second, allowing users to translate mechanical power measurements in legacy imperial units into thermal power units commonly used in heating and energy systems.
How to Use This Tool?
-
Enter the numerical value in foot pound-force per hour
-
Select foot pound-force/hour as the input unit and Btu (th)/second as the output unit
-
Click the convert button to see the equivalent thermal power measurement
-

Key Features
-
Converts small mechanical power units (foot pound-force/hour) into thermal energy units (Btu (th)/second)
-
Supports engineering and HVAC-related power conversions
-
Browser-based and user-friendly interface for quick calculations
-
Includes examples to illustrate conversion usage
-
Helps compare legacy mechanical power with modern thermal power units
Examples
-
Converting 100 foot pound-force/hour results in approximately 3.572 × 10⁻⁵ Btu (th)/second
-
Converting 5000 foot pound-force/hour results in approximately 0.001786 Btu (th)/second
Common Use Cases
-
Expressing very small mechanical power rates in engineering documents for legacy imperial-system machinery
-
Specifying heat transfer rates in HVAC equipment capacity ratings
-
Converting historical mechanical power data to thermal power for performance comparisons
-
Analyzing building services and industrial energy systems that involve both mechanical and thermal measurements
Tips & Best Practices
-
Ensure steady-state conditions when using this conversion as it assumes constant power rates
-
Use this tool to integrate mechanical work data with thermal energy system ratings accurately
-
Apply conversions when updating legacy imperial unit specifications to modern thermal units
-
Check units carefully to maintain consistency in engineering calculations
Limitations
-
The foot pound-force/hour unit represents very small power levels and is not widely used in modern applications
-
Btu (th)/second measures thermal energy transfer while foot pound-force/hour quantifies mechanical work, so interpretation depends on context
-
This conversion presumes steady-state conditions and may not suit rapidly changing power scenarios or purely mechanical processes without thermal equivalence
Frequently Asked Questions
-
What does foot pound-force/hour measure?
-
It measures a small mechanical power rate representing one foot-pound-force of work performed or energy transferred every hour.
-
What is Btu (th)/second used for?
-
Btu (th)/second quantifies the rate of thermal energy transfer, commonly applied in heating, cooling, and energy-conversion systems.
-
Why convert foot pound-force/hour to Btu (th)/second?
-
To translate mechanical work data from legacy imperial units into thermal power units for use in HVAC and energy system analyses.
Key Terminology
-
Foot pound-force/hour
-
A non-SI unit of power representing one foot-pound-force of work performed or energy transferred every hour.
-
Btu (th)/second
-
A unit of power measuring the rate of thermal energy transfer equal to one thermochemical British thermal unit per second.
