The megahertz is one million hertz, used to express FM radio, Wi-Fi and older computer processor speeds.
It became the practical standard unit for expressing high-frequency signals as radio and telecommunications technology developed.
Measurement system: International System of Units (SI, multiple unit). SI equivalent: 1 MHz = 1,000,000 Hz.
