<P> The hertz ( symbol : Hz ) is the derived unit of frequency in the International System of Units ( SI ) and is defined as one cycle per second . It is named for Heinrich Rudolf Hertz , the first person to provide conclusive proof of the existence of electromagnetic waves . Hertz are commonly expressed in multiples : kilohertz ( 10 Hz , kHz ) , megahertz ( 10 Hz , MHz ) , gigahertz ( 10 Hz , GHz ) , terahertz ( 10 Hz , THz ) , petahertz ( 10 Hz , PHz ) , and exahertz ( 10 Hz , EHz ) . </P>
