MHz: meaning, definitions and examples
📡
MHz
[ ɛm ɛtʃ z ]
scientific measurement
MHz, or megahertz, is a unit of frequency equal to one million hertz. It is commonly used to measure the frequency of electromagnetic waves, including radio waves, and in digital electronics as the clock speed of microprocessors. This term is frequently used in contexts such as telecommunications and audio technology.
Synonyms
frequency unit, megahertz
Examples of usage
- The radio station broadcasts at a frequency of 101.5 MHz.
- My laptop's processor runs at 2.5 GHz, which is equivalent to 2500 MHz.
- The Wi-Fi router operates on both 2.4 GHz and 5 GHz bands, which are 2400 MHz and 5000 MHz, respectively.
- Most FM radio stations operate in the range of 88 MHz to 108 MHz.
- The performance of the device can be affected by its operating frequency, measured in MHz.

Etymology
The term 'megahertz' was first introduced in the early 20th century as a way to denote frequencies in the megahertz range, especially as technologies like radio and television became more widespread. The prefix 'mega-' comes from the Greek word 'megas,' meaning 'great' or 'large,' which was adopted into the International System of Units (SI) to signify a factor of one million. The hertz, named after the German physicist Heinrich Hertz, was established as the unit of frequency in 1930 and is defined as one cycle per second. Combining the two, 'megahertz' became a standard term for frequency measurement in telecommunications and broadcasting, signifying an important unit in the emerging technologies of the 20th century and beyond.
