Formulas

Torque (in-lbs) = HP x 63025 / RPM
HP = Torque x RPM / 63,025
RPM = HP x 63,025 / Torque (in-lbs)


Torque  -  HP:  x 63025 / RPM: 0
HP  -  Torque: x RPM: / 63025 0
RPM  -  HP: x 63025 / Torque: 0

 HP - Input motor horsepower
RPM - RPM at output shaft

Example: 20 HP at 900 output PRM = 20 x 63,025 / 900 = 1,400 pound-inches of torque
