What Is This Tool?
This tool converts power values from pound-foot per hour, an imperial unit representing very low mechanical power, to kilojoule per second, a metric unit equivalent to kilowatt commonly used for electrical and mechanical power ratings. It facilitates the translation of legacy unit measures into modern SI units.
How to Use This Tool?
-
Enter the power value measured in pound-foot/hour into the input field
-
Select pound-foot/hour as the from unit and kilojoule/second as the to unit
-
Initiate the conversion process to get the result in kilojoule/second
-
Use the output for comparison, documentation, or further calculations
Key Features
-

-
Supports legacy imperial units and modern SI unit integration
-
Browser-based and user-friendly interface for quick conversions
-
Includes practical examples demonstrating typical conversions
Examples
-
100 pound-foot/hour converts to 3.7661609676e-5 kilojoule/second
-
5000 pound-foot/hour converts to 0.00188308048379 kilojoule/second
Common Use Cases
-
Expressing very low continuous mechanical output in existing imperial units
-
Documenting power specifications of vintage or historical equipment
-
Estimating slow mechanical work rates such as hand-crank or winch outputs
-
Rating electrical or mechanical power of devices in modern SI units
-
Quantifying thermal energy transfer in HVAC and boiler systems
-
Specifying turbine or engine power in industrial settings
Tips & Best Practices
-
Always verify the input units before conversion to ensure accuracy
-
Use this tool primarily for low power rates common in legacy or vintage contexts
-
Utilize converted values to standardize documentation or compare with SI-based data
-
Remember that this conversion suits low power and may not apply well for high power scenarios
Limitations
-
Precision depends on the rounding of conversion constants
-
Pound-foot/hour measures very low power making it unsuitable for large power evaluations
-
Primarily applicable to legacy or historical mechanical power contexts
-
Not ideal for real-time measurements in industrial high power applications
Frequently Asked Questions
-
What does pound-foot/hour measure?
-
It measures mechanical power representing the rate of work done in imperial units as one foot-pound force per hour, typically used for very low continuous mechanical output.
-
Why convert pound-foot/hour to kilojoule/second?
-
Converting allows comparison and integration of low power ratings from legacy imperial units to widely used modern SI units for scientific, industrial, and documentation purposes.
-
Is kilojoule/second equivalent to any common power unit?
-
Yes, kilojoule per second equals one kilowatt, making it a standard unit to express electrical or mechanical power.
Key Terminology
-
Pound-foot/hour [lbf*ft/h]
-
An imperial unit of power equal to one foot-pound force of work done per hour; used for expressing very low mechanical power rates.
-
Kilojoule/second [kJ/s]
-
A metric power unit representing the transfer rate of 1,000 joules per second, equivalent to one kilowatt.
-
Conversion Rate
-
The factor used to translate values from pound-foot/hour to kilojoule/second, specifically 1 lbf*ft/h equals 3.7661609675818e-7 kJ/s.
