What Is This Tool?
This converter enables you to transform power values measured in electric horsepower into pound-foot per hour, an imperial unit that illustrates mechanical work rates. It is designed for users working with electric motors as well as those dealing with legacy imperial power specifications.
How to Use This Tool?
-
Enter the numeric value of power in electric horsepower
-
Select horsepower (electric) as the input unit
-
Choose pound-foot per hour [lbf*ft/h] as the output unit
-
Click convert to obtain the equivalent power in pound-foot per hour
Key Features
-
Converts power from electric horsepower to pound-foot per hour (lbf*ft/h)
-
Based on exact conversion rates recognized in engineering practice
-
Useful for vintage machinery and low-power mechanical device measurements
-
Browser-based and easy to operate without specialized software
Examples
-
1 horsepower (electric) converts to 1,980,796.91 pound-foot/hour [lbf*ft/h]
-
0.5 horsepower (electric) converts to 990,398.45 pound-foot/hour [lbf*ft/h]
Common Use Cases
-
Determining motor output power from electric horsepower ratings
-
Documenting power for small mechanical equipment using legacy imperial units
-
Comparing electric motor ratings to traditional mechanical power measurements
-
Estimating slow mechanical work rates such as hand-crank or winch devices
Tips & Best Practices
-
Verify unit selection carefully to avoid incorrect conversions
-
Use this tool for equipment with low power outputs or historical specifications
-
Reference motor nameplates and manufacturer data for accurate input values
-
Understand the limitations of imperial units for high power applications
Limitations
-
Pound-foot per hour unit indicates very low power, unsuitable for high-power devices
-
Conversion relies on legacy definitions which may affect precision accuracy
-
Modern engineering commonly uses SI units for consistency and clarity
Frequently Asked Questions
-
Why convert from electric horsepower to pound-foot per hour?
-
Conversion is needed to express power in traditional imperial units, particularly for vintage or small-scale mechanical equipment that originally used these units.
-
What industries benefit from this conversion?
-
Mechanical restoration, vintage machinery maintenance, horology (clockmaking), and manufacturing scenarios involving historical equipment ratings.
-
Is pound-foot per hour suitable for high-power calculations?
-
No, pound-foot per hour denotes very small power values and is impractical for high-power applications.
Key Terminology
-
Horsepower (electric)
-
A power unit equal to exactly 746 watts, used for rating electric motors and drives.
-
Pound-foot/hour [lbf*ft/h]
-
An imperial unit of power representing one foot-pound force of work done per hour, used for expressing low mechanical power.
