Megahertz (MHz)
A megahertz is one million hertz. FM radio uses 88–108 MHz, microcontrollers run at 8–200 MHz and RAM speeds are quoted in MHz (strictly MT/s).
Symbol: MHz
Quantity: frequency and rotational speed
SI relation: 1 MHz = 1000000 Hz (exact)
Derivation: 1 MHz = 10⁶ Hz.
Exact: yes, by definition
Typical uses
- FM radio and TV
- Microcontroller and RAM clocks
- ISM radio bands (433, 868, 915 MHz)
