Power and Torque: Understanding the Relationship

11/03/2011  POWER is CALCULATED from torque and RPM, by the following equation: HP = Torque x RPM ÷ 5252 (At the bottom of this page, the derivation of that equation is shown, for anyone interested.) An engine produces POWER by providing a ROTATING SHAFT which can exert a given amount of TORQUE on a load at a given RPM. The amount of TORQUE the engine can exert usually varies with RPM. TORQUE.
