megahertz [MHz] to gigahertz [GHz] Converter

Quick Reference

1 megahertz (MHz) = 0.001 gigahertz (GHz)

1 gigahertz (GHz) = 1000 megahertz (MHz)

How to Convert megahertz to gigahertz

1 MHz = 0.001 GHz
1 GHz = 1000 MHz

To convert megahertz to gigahertz, divide the value by 1000 (equivalently, multiply by 0.001). To convert gigahertz back to megahertz, multiply by 1000.

Example: convert 10 MHz to GHz:
10 MHz = 10 x 0.001 = 0.01 GHz

↔ Convert gigahertz to megahertz

megahertz

Definition: A megahertz (symbol: MHz) is a unit of frequency equal to one million (1,000,000) hertz (Hz). The hertz, in turn, is the SI unit of frequency, defined as one cycle per second.

History/origin: The megahertz is derived from the hertz, named after the German physicist Heinrich Hertz, who made significant contributions to the understanding of electromagnetic waves. The prefix 'mega-' denotes a factor of 10<sup>6</sup>, adhering to the SI system of units.

Current use: Megahertz is commonly used to measure frequencies in radio broadcasting (e.g., FM radio), television signals, wireless communication (e.g., Wi-Fi), and the clock speeds of computer processors. It is a standard unit in telecommunications, computing, and electronics.

gigahertz

Definition: A gigahertz (symbol: GHz) is a unit of frequency equal to one billion (1,000,000,000) hertz (Hz). The hertz, in turn, is the SI unit of frequency, defined as one cycle per second.

History/origin: The gigahertz is derived from the hertz, named after the German physicist Heinrich Hertz, who made significant contributions to the understanding of electromagnetic waves. The prefix 'giga-' denotes a factor of 10<sup>9</sup>, adhering to the SI system of units.

Current use: Gigahertz is primarily used to measure the clock speeds of modern computer processors, the frequencies of wireless communication technologies (e.g., 5G cellular networks), and radar systems. It represents very high-frequency signals and operations.
