Cps vs. Hertz

initialism of character(s) per second

The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI) and is defined as one cycle per second. It is named after Heinrich Rudolf Hertz (1857-1894), the first person to provide conclusive proof of the existence of electromagnetic waves.

the unit of frequency; one Hertz has a periodic interval of one second

the SI unit of frequency, equal to one cycle per second.

A unit of frequency equal to one cycle per second. See Table at measurement.

In the International System of Units, the derived unit of frequency; one (period or cycle of any periodic event) per second. Symbol: Hz

a unit of frequency equal to one cycle per second; it is abbreviated Hz. It is commonly used to specify the frequency of radio waves, and also the clock frequencies in digital computers. For these applications, kilohertz and megahertz are the most commonly used units, derived from hertz.

German physicist who with James Franck proved the existence of the stationary energy states postulated by Bohr (1887-1975)
