How do you calculate mechanical horsepower?

To find the mechanical horsepower of a motor, use the
horsepower formula:
HP = ( Torque x RPM) / 63025

Torque is measured in Inch Pounds

Example: The mechanical horsepower of a motor with 1000 in/lbs
of output torque and an output speed of 2000 RPM is:

HP = (1000 x 2000) / 63025

Calculated out this gives a mechanical horsepower of 31.7334.
(rounded to the nearest 10,000th)
