What Is This Tool?
This unit converter transforms values from foot pound-force per hour, a legacy imperial power unit, into milliwatt, a precise SI unit commonly used in modern engineering for low power measurements.
How to Use This Tool?
-
Enter the power value in foot pound-force per hour
-
Select foot pound-force/hour as the input unit
-
Choose milliwatt [mW] as the output unit
-
Click convert to get the equivalent power in milliwatts
Key Features
-
Converts small mechanical power values from foot pound-force/hour to milliwatt [mW]
-
Uses the exact conversion rate of 1 ft·lbf/hr = 0.3766160968 mW
-
Browser-based and easy to use without any installation
-
Supports engineering and technical fields involving mechanical, electrical, and optical power
Examples
-
10 foot pound-force/hour equals about 3.766160968 milliwatts
-
5 foot pound-force/hour converts to approximately 1.883080484 milliwatts
Common Use Cases
-
Expressing very small mechanical power in standard SI units
-
Updating legacy imperial power data to modern metric units
-
Comparing mechanical power with electrical and optical power outputs in engineering reports
Tips & Best Practices
-
Use this tool to ensure consistent power unit representation in engineering documentation
-
Verify input values to maintain conversion accuracy
-
Remember the foot pound-force/hour measures power over one hour, so it's not for instantaneous power readings
Limitations
-
Foot pound-force/hour is a legacy unit less suitable for precise modern calculations
-
Conversion relies on exact constants; minor rounding differences may occur
-
Not appropriate for power measurements over short time intervals
Frequently Asked Questions
-
What does foot pound-force per hour measure?
-
It measures mechanical power representing one foot-pound-force of work done or energy transferred every hour.
-
Why convert foot pound-force/hour to milliwatt?
-
Converting to milliwatt helps express small mechanical power rates in the SI unit common in electrical, optical, and RF applications.
-
Can this conversion be used for instantaneous power?
-
No, since foot pound-force/hour measures power over an hour, it's not suitable for instantaneous power measurements.
Key Terminology
-
Foot pound-force/hour
-
A legacy imperial unit of power expressing one foot-pound-force of energy transferred every hour.
-
Milliwatt (mW)
-
One thousandth of a watt, measuring the rate of energy transfer commonly used for low power electrical and optical devices.
