Although it's measured in the same units as work, due to the radial nature of the force's application.Torque is a finite quantity that can be measured. Power is not...power is nothing more than a time rate of change expression of instantaneous force (or torque, as the case may be). You cannot measure power. You can only derive it mathematically once you have measured the force at work. Torque is the actual force applied to the crank by the pressure of expanding combustion gases on the piston crowns. At any given rotational speed or innstant, you can measure this force. Once you have done so, you derive HP using: HP = TQ*5250/RPM
