## Hertz Definition and Usage

Hertz is formally defined as the frequency equalling one cycle per second.

The hertz is the SI derived unit for frequency in the metric system. Hertz can be abbreviated as *Hz*, for example 1 hertz can be written as 1 Hz.

Frequency in hertz can be expressed using the formula:
Hz = CyclesTime_{s}

### Background and Origin

The unit is named after German physicist Heinrich Hertz, who proved the existence of the electromagnetic waves. The unit was introduced in 1930 and the hertz eventually replaced cycles per second as the standard unit of frequency in the 1960s and 1970s.

### Uses

Hertz are commonly used to measure sine waves in music, radio, and other audio applications. The unit is also used to measure the speed of electronics and computer processing.
