Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio - and audio-related applications.

Main article: SI derived unit. The system allows for an unlimited number of additional units, called derived units, which can always be represented as products of powers of the base units, possibly with a nontrivial numeric multiplier. When that multiplier is one, the unit is called a coherent derived unit.

As any SI unit, Hz can be prefixed; commonly used multiples are kHz (kilohertz, 10 3 Hz), MHz (megahertz, 10 6 Hz), GHz (gigahertz, 10 9 Hz) and THz (terahertz, 10 12 Hz). One hertz simply means one cycle per second (typically that which is being counted is a complete cycle); 100 Hz means one hundred cycles per second, and so on.
The hertz is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second (s). One hertz is the reciprocal of one second (1/s). The hertz is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves.
The dimension of the unit hertz is 1/time (1/T). Expressed in base SI units, the unit is 1/second (1/s). In English, "hertz" is also used as the plural form. As an SI unit, Hz can be prefixed; commonly used multiples are kHz (kilohertz,), MHz (megahertz,), GHz (gigahertz,) and THz (terahertz,). One hertz simply means "one cycle per second ...
