What Is This Tool?
This converter transforms values from foot pound-force per minute, a unit used to measure small mechanical power in imperial units, into horsepower (550 ft*lbf/s), an established imperial power unit commonly applied in engine and equipment power ratings.
How to Use This Tool?
-
Enter the power value in foot pound-force per minute.
-
Select foot pound-force per minute as the input unit.
-
Choose horsepower (550 ft*lbf/s) as the output unit.
-
Click convert to get the equivalent horsepower value.
Key Features
-
Converts small mechanical power values from foot pound-force per minute to horsepower (550 ft*lbf/s).
-
Ideal for legacy engineering documents and imperial unit contexts.
-
Browser-based and simple to use with quick input and output results.
-
Helps in comparing power ratings of engines, pumps, and motors.
Examples
-
100 foot pound-force per minute equals 0.0030303 horsepower (550 ft*lbf/s).
-
5000 foot pound-force per minute equals 0.151515 horsepower (550 ft*lbf/s).
Common Use Cases
-
Converting small mechanical power values in legacy or imperial engineering documents.
-
Estimating power from torque measured in foot-pounds at slow speeds.
-
Rating power for small hand-tools, manual winches, or low-power pumps in imperial units.
-
Specifying engine and equipment power for automotive or industrial applications.
Tips & Best Practices
-
Ensure units are correctly selected before converting for accurate results.
-
Use this tool to translate legacy measurements into familiar horsepower ratings.
-
Consider the very small output values and interpret decimal results carefully.
-
Be aware of possible rounding differences due to unit system conversions.
Limitations
-
Foot pound-force per minute measures very small power, so converted horsepower values are often extremely small decimals.
-
Precision depends on the conversion constants; rounding errors may affect exact values.
-
Differences between imperial and SI unit systems can introduce minor discrepancies.
Frequently Asked Questions
-
What is foot pound-force per minute used for?
-
It is a non‑SI unit measuring mechanical power, commonly used in legacy or imperial engineering documents for small power applications like hand-tools or manual equipment.
-
Why convert foot pound-force per minute to horsepower (550 ft*lbf/s)?
-
Converting to horsepower helps standardize power ratings and makes it easier to compare or specify engines, pumps, and motors in familiar imperial units.
-
Are there any limitations in this conversion?
-
Yes, since foot pound-force per minute represents very small power values, the converted horsepower results are small decimals, and differences between unit systems may cause rounding errors.
Key Terminology
-
Foot pound-force per minute
-
A non-SI unit measuring mechanical power, representing one foot-pound-force of work performed each minute.
-
Horsepower (550 ft*lbf/s)
-
An imperial power unit defined as 550 foot-pound-force per second, commonly used for rating engines and mechanical equipment.
-
Mechanical power
-
The rate at which mechanical work is performed or energy is transferred.
