What Is This Tool?
This converter helps translate power measurements from pound-foot per hour, a legacy imperial mechanical power unit, to picojoule per second, a modern SI unit used for extremely low power levels. It's useful for bridging older mechanical ratings with precise, ultra-low power electronic standards.
How to Use This Tool?
-
Enter the value in pound-foot/hour you wish to convert
-
Select the output unit picojoule/second if not pre-selected
-
Click convert to see the equivalent power in picojoule/second
-
Use the result for engineering, scientific research, or documentation purposes
Key Features
-
Converts from pound-foot/hour (lbf·ft/h) to picojoule/second (pJ/s)
-
Handles conversion of very low mechanical power units to ultra-fine SI units
-
Browser-based and easy to use with instantaneous results
-
Supports applications in vintage equipment analysis and nano-scale power measurements
Examples
-
2 lbf*ft/h = 2 × 376616096.75818 pJ/s = 753232193.51636 pJ/s
-
0.5 lbf*ft/h = 0.5 × 376616096.75818 pJ/s = 188308048.37909 pJ/s
Common Use Cases
-
Expressing very low continuous mechanical output in legacy imperial units such as small clock or gear-train power
-
Documenting historical or vintage equipment power ratings with imperial foot-pound units
-
Estimating slow mechanical work rates like hand-crank or winch rates when converting to SI
-
Specifying continuous power draw of ultra-low-power microcontrollers and sensors
-
Reporting optical power in sensitive photonics and single-photon detection systems
Tips & Best Practices
-
Carefully enter values to avoid precision loss due to the large conversion factor
-
Use this tool to interpret legacy mechanical power data in modern scientific contexts
-
Apply converted results where precise, ultra-small power quantification is needed
-
Understand the units’ domains: pound-foot/hour for mechanical legacy, picojoule/second for nanoelectronics and photonics
-
Verify results with specialized instrumentation when implementing in sensitive applications
Limitations
-
Pound-foot/hour is rarely used in modern settings, so legacy data may have uncertainties
-
Large numeric conversion values require careful numerical handling to prevent rounding errors
-
Picojoule/second unit applications usually require advanced equipment, limiting general usage
Frequently Asked Questions

No, it is mainly relevant for scientific research and specialized industries involving vintage mechanical devices and ultra-low power electronics.
Key Terminology
-
Pound-foot per hour (lbf·ft/h)
-
An imperial unit of power representing one foot-pound force of work done per hour, indicating mechanical power.
-
Picojoule per second (pJ/s)
-
A unit of power equal to 10⁻¹² joules per second, used to measure extremely low continuous power levels.
-
Mechanical work rate
-
The rate at which work is done or energy is transferred mechanically, often measured in foot-pounds per unit time in imperial units.
