Cycles per Minute to Revolutions per Minute Converter

Cycles per minute (cpm) is a unit of frequency representing the number of complete cycles of a periodic phenomenon occurring in one minute. It's used for moderate-frequency periodic processes and mechanical systems.

Cycles per minute developed for describing periodic processes that occur at moderate rates, particularly in mechanical systems, industrial processes, and biological applications where minute-based measurements were more practical than second-based measurements.

CPM is used in industrial process control, mechanical systems, biological monitoring, and applications where periodic events occur at moderate rates. It's found in process equipment specifications, biological rhythm measurements, and industrial automation systems.

Revolutions per minute (rpm) is a unit of rotational frequency representing the number of complete rotations around a fixed axis in one minute. It's one of the most common units for measuring rotational speed in mechanical systems.

RPM became standard with the development of mechanical machinery during the Industrial Revolution. It provided an intuitive way to measure and specify rotational speeds for engines, motors, and machinery, becoming universally adopted in mechanical engineering.

RPM is extensively used in automotive engines, electric motors, machinery, and mechanical systems. It's standard for engine specifications, motor ratings, turntable speeds, and virtually all rotating mechanical equipment specifications.
