We explain what a frequency is and how to measure this magnitude. In addition, the different meanings of this term.

The frequency must be measured in hertz.## What is frequency?

Frequency is a quantity that measures the number of repetitions that an event can have per unit ofweather.

He does (International System of Units), which is the unit system used by most countries in the world, says that frequency must be measured in hertz (Hz).

One Hertz is the frequency of a periodic event whose repetition occurs once per second, this unit also understood as cycle per second (cps). The derivation of Hertz is given in honor of the physicist Heinrich Rudolf Hertz.

But there is not only the hertz as a unit of measurement of frequency. There are also other units such as revolutions per minute (rpm); beats per minute (bpm), used rather to measure heartbeat and musical tempo; and radians per second (rad / s)

Within the field of telecommunications, the frequency is used to establish the bands through which each station broadcasts.

In statistics, on the other hand, it is called*frequency* to the number of components included within an interval, with a specific distribution.
