Frequently Asked Questions
-
What does pound-foot per second measure?
-
It measures mechanical power as work done per second in Imperial units, representing torque multiplied by rotational speed.
-
How is electric horsepower defined?
-
Electric horsepower is defined as exactly 746 watts, used to rate power of electric motors and drives.
-
Why convert pound-foot/second to electric horsepower?
-
To express mechanical power in terms of electric motor ratings for equipment specification, comparison, and electrical system sizing.
Key Terminology
-
Pound-foot/second
-
An Imperial unit of power representing one pound-force foot of work performed per second, used to measure mechanical power.
-
Horsepower (electric)
-
A unit of power exactly equal to 746 watts, used for rating electric motors and related equipment.
