Torque

Torque is the turning moment or twisting effort in a shaft or an object that tends to cause rotation. It is the measure of rotational force and is expressed in foot-pounds.

Torque = force in pounds x radius in inch or foot

Torque (pound-inch) =  63,025 x hp
                                        rpm

Torque (pound-foot) = 5,252 x hp
                                      rpm

Horsepower =  TORQUE (lb-in) x rpm
                                 63,025

Horsepower =  TORQUE (lb-ft) x rpm
                                 5,252

Horsepower to Torque Conversion Table

To compute torque at any horsepower, multiply torque values above by horsepower required.

Example:
10 hp @ 580 rpm, torque = 10 x 109, or 1,090 lb-ins
1/2 hp @ 100 rpm, torque = 1/2 x 630, or 315 lb-ins

For intermediate speeds, approximate the torque from table, or apply standard torque formula above.
