-
Electric horsepower is fixed at exactly 746 watts, differing from other horsepower types
-
Accurate conversion depends on correctly interpreting the units to avoid mixing power types
Frequently Asked Questions
-
What does foot pound-force per second measure?
-
It measures mechanical power as one pound-force applied through a one-foot displacement every second.
-
Why convert foot pound-force per second to electric horsepower?
-
To express mechanical power values in a common electric motor rating for consistent specification and comparison.
-
Is electric horsepower the same as mechanical horsepower?
-
No, electric horsepower is defined as exactly 746 watts and may differ from mechanical or metric horsepower.
Key Terminology
-
Foot pound-force/second
-
An imperial unit of mechanical power equal to one pound-force applied through a one-foot displacement each second.
-
Horsepower (electric)
-
A unit of power rating for electric motors fixed at exactly 746 watts, representing electrical power conversion equivalent to mechanical horsepower.
