Horsepower/Torque

Torque is the product of the magnitude of the force and the perpendicular distance from the force to the axis of rotation (i.e. the pivot point).  The torque equation calculates the horsepower an engine produces given the torque and RPM, or the torque produced given horsepower and RPM. If you are inputting a known torque be sure that the units are in pound-feet.
