What Is This Tool?
This converter allows users to transform power values expressed in foot pound-force per second into pound-foot per hour, both imperial units used for mechanical power measurements in different time scales.
How to Use This Tool?
-
Enter the value measured in foot pound-force per second into the input field
-
Select pound-foot per hour as the target unit
-
Click the convert button to get the equivalent power in pound-foot/hour
-
Use the result to compare or report power levels in slow or legacy mechanical systems
Key Features
-
Converts power units between foot pound-force/second and pound-foot/hour accurately
-
Simple interface suitable for mechanical engineering and historical data applications
-
Supports calculations involving small mechanical power outputs or slow mechanical work rates
-
Browser-based tool requiring no installations or advanced setup
Examples
-
Converting 2 foot pound-force/second results in 7200 pound-foot/hour [lbf*ft/h]
-
A value of 0.5 foot pound-force/second equals 1800 pound-foot/hour [lbf*ft/h]
Common Use Cases
-
Specifying small mechanical power for hand tools or minor engines in imperial units
-
Recording power output in historical or vintage equipment specifications
-
Estimating low-rate mechanical work such as hand-crank or slow winch operations
-
Comparing mechanical power outputs in different legacy imperial units
Tips & Best Practices
-
Double-check unit selections before converting to ensure correct output
-
Use this converter mainly for low power rates since pound-foot/hour represents very small outputs
-
For modern applications, consider converting to SI units such as watts for standardized reporting
-
Be cautious with historical data as unit definitions might vary slightly over time
Limitations
-
Pound-foot/hour is suitable only for very low power measurements
-
Not practical for high power mechanical systems
-
Historical records might have slight inconsistencies in unit definitions
-
Less common in current engineering practice, so SI conversions are often preferred
Frequently Asked Questions
-
What does foot pound-force per second measure?
-
It measures mechanical power as one pound-force moving through one foot every second, commonly used for small mechanical outputs in imperial units.
-
Why convert foot pound-force/second to pound-foot/hour?
-
Converting allows expressing power output measured over hours instead of seconds, useful for slow or legacy mechanical work contexts.
-
Is pound-foot/hour widely used in modern engineering?
-
No, it is mostly applied in historical or niche cases; modern engineering typically uses SI units like watts for power measurement.
Key Terminology
-
Foot pound-force/second
-
An imperial unit of mechanical power equal to one pound-force applied through a one-foot displacement every second.
-
Pound-foot/hour
-
An imperial unit of power representing one foot-pound force of work done per hour, used for very low continuous mechanical power outputs.
-
Mechanical horsepower
-
A unit of power defined as 550 foot pound-force per second, often used for engine power ratings.
