# ››Definition: Gigahertz

The SI prefix "giga" represents a factor of 109, or in exponential notation, 1E9.

So 1 gigahertz = 109 .

The definition of a hertz is as follows:

The hertz (symbol Hz) is the SI unit of frequency. It is named in honour of the German physicist Heinrich Rudolf Hertz who made some important contributions to science in the field of electromagnetism.

# ››Definition: Megahertz

The SI prefix "mega" represents a factor of 106, or in exponential notation, 1E6.

So 1 megahertz = 106 .

The definition of a hertz is as follows:

The hertz (symbol Hz) is the SI unit of frequency. It is named in honour of the German physicist Heinrich Rudolf Hertz who made some important contributions to science in the field of electromagnetism.
