The full form of RPM is Revolutions Per Minute. It involves figuring out how frequently an object rotates or how many revolutions or rotations it makes each minute. It illustrated how frequently an involuntary component spins around its axis in a minute. RPM, thus, is the frequency or speed of an involuntary object’s rotation about a fixed axis, such as the crankshaft of an engine, a turbine power generator, a DVD or CD player, or a turbocharger.
