What Is This Tool?
This converter transforms power values from pound-foot per hour, an imperial unit representing mechanical work done per hour, into newton meter per second, the SI unit equivalent representing watts.
How to Use This Tool?
-
Enter the power value in pound-foot per hour.
-
Select the source unit as pound-foot/hour [lbf*ft/h].
-
Select the target unit as newton meter/second.
-
Click convert to obtain the equivalent power in newton meters per second.
Key Features
-
Converts legacy imperial power units to standard SI units for engineering use.
-
Supports understanding of very low power values in modern terms.
-
Ideal for evaluating mechanical power in historical and low-output devices.
Examples
-
10 lbf*ft/h equals 0.003766161 newton meter/second.
-
100 lbf*ft/h equals 0.03766161 newton meter/second.
Common Use Cases
-
Translating legacy imperial mechanical power measures into SI units for precise analysis.
-
Restoring or analyzing historical mechanical equipment specifications.
-
Assessing slow mechanical power outputs like clocks, gear trains, or hand-cranks.
Tips & Best Practices
-
Ensure input values are accurate for low-power measurements to get meaningful results.
-
Use this conversion when dealing with vintage machinery to bridge imperial and SI standards.
-
Remember that fractional outputs in watts are typical when converting from lbf*ft/h.
Limitations
-
Conversion values represent very low power and are typically fractional.
-
The unit conversion approximates average mechanical power, not instantaneous peaks.
-
Precision is necessary as the measurement reflects slow mechanical work rates.
Frequently Asked Questions
-
What does one pound-foot per hour represent?
-
It denotes the rate of mechanical work equal to one foot-pound force done every hour, expressed in imperial units.
-
Why convert pound-foot/hour to newton meter/second?
-
To translate older imperial power ratings into SI units for modern engineering and accurate equipment specification.
-
Is the conversion suitable for dynamic power measurements?
-
No, this conversion reflects an average power rate and may not capture instantaneous power peaks in dynamic systems.
Key Terminology
-
Pound-foot/hour (lbf·ft/h)
-
An imperial unit of power equal to one foot-pound force of work performed per hour, used for very low power rates.
-
Newton meter per second
-
An SI unit of power equal to one joule per second (watt), representing the rate of doing mechanical work or energy transfer.
