Hertz
- The SI unit of frequency is the hertz (Hz), named after the German physicist Heinrich Hertz by the International Electrotechnical Commission in 1930. It was adopted by the CGPM (Conférence générale des poids et mesures) in 1960, officially replacing the previous name, cycle per second (cps).

The standard unit for frequency is considering the number 'per second', which is called 'hertz, Hz', but this comes from the fundamental unit 'second'. Derived units include: Name
The unit of frequency is the Hertz (Hz), named after the German physicist Heinrich Hertz. One Hertz is equivalent to one cycle per second. In the International System of Units (SI), the unit is defined as \( \text{s}^{-1} \) (inverse seconds).

Frequency (symbol f), most often measured in hertz (symbol: Hz), is the number of occurrences of a repeating event per unit of time. [1] It is also occasionally referred to as temporal frequency for clarity and to distinguish it from spatial frequency.
3 days ago · Frequency is usually expressed in the hertz unit, abbreviated Hz. One kilohertz (kHz) is 1,000 Hz, and one megahertz (MHz) is 1,000,000 Hz. In spectroscopy, another unit of frequency that is sometimes used is the wavenumber, the number of waves in a unit of distance.
Unit of Frequency. Frequency refers to the number of complete occurrences per unit time. It basically describes the number of waves that pass a fixed area at a certain point in time. Besides, frequency mainly involves cyclical processes like oscillations, rotation, or waves.
