The hertz
The hertz (Hz) is the SI derived unit of frequency, equal to one cycle per second. It is the universal unit for sound pitch, electrical AC frequency, processor clock speed (in multiples), and radio and wireless signal frequencies.
Hertz to Megahertz Converter
1 Hz = 1.0000 × 10^−6 MHz (hertz → megahertz)
1 Hz = 1.0000 × 10^−6 MHz
1 hertz equals 1.0000 × 10^−6 megahertz. To convert hertz to megahertz, multiply the hertz value by 1.0000 × 10^−6. For quick reference: 1 Hz = 1.0000 × 10^−6 MHz, 5 Hz = 5.0000 × 10^−6 MHz, 10 Hz = 1.0000 × 10^−5 MHz, 100 Hz = 0.0001 MHz.
Formula
Megahertz = Hertz × 1.0000 × 10^−6Quick
