Megahertz (MHz)
The megahertz (symbol: MHz, often styled as mHz in non-case-sensitive systems) is an SI unit of frequency equal to one million hertz (10^6 Hz). Established in 1930 by the International Electrotechnical Commission, it measures high-frequency electromagnetic waves and processing speeds. Megahertz is widely used in radio broadcasting (such as FM radio), telecommunications, microprocessor clock rates, and medical ultrasound imaging.
