Hertz to Cycles per Minute Converter

A hertz (Hz) is the SI base unit of frequency, defined as one cycle per second. It represents the fundamental measure of frequency, named after German physicist Heinrich Hertz, and forms the basis for all other frequency measurements.

The hertz was named after Heinrich Hertz in 1930, who proved the existence of electromagnetic waves. It was adopted as the SI unit of frequency in 1960, replacing the older term 'cycles per second' and providing a unified measure for all periodic phenomena.

Hertz is universally used for measuring all types of frequencies, from sound waves to electromagnetic radiation. It's fundamental in physics, engineering, music, and technology, serving as the base unit for all frequency measurements and calculations.

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.
