Hertz to Cycles per Second 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 second (cps) is a unit of frequency representing the number of complete cycles of a periodic phenomenon occurring in one second. It's essentially equivalent to hertz but predates the modern SI terminology.

Cycles per second was the original term used to describe frequency before the adoption of the hertz in 1960. It was widely used in early electronics, radio, and physics literature, providing a descriptive term for periodic phenomena.

Cycles per second is rarely used in modern applications, having been replaced by hertz in scientific and technical contexts. It may still appear in historical literature, educational materials, or informal descriptions of frequency.
