How to Convert Megahertz to Gigahertz
To convert megahertz to gigahertz, multiply the frequency by the following conversion ratio: 0.001 gigahertz/megahertz.
Since one megahertz is equal to 0.001 gigahertz, you can use this simple formula to convert:
The frequency in gigahertz is equal to the frequency in megahertz multiplied by 0.001.
For example, here's how to convert 3200 megahertz to gigahertz using the formula above.
How Many Gigahertz Are in a Megahertz?
There are 0.001 gigahertz in a megahertz, which is why we use this value in the formula above.
Our megahertz to gigahertz calculator automatically converts your frequency measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Megahertz and gigahertz are both units used to measure frequency. Keep reading to learn more about each unit.
What Is a Megahertz?
A megahertz is a unit of frequency equal to 1,000,000 hertz (Hz), the base unit for frequency. Equal to 1,000,000 Hz. [1]
The megahertz is classified as a metric and SI-compatible unit of frequency. Megahertz can be abbreviated as MHz; for example, 1 megahertz can be written as 1 MHz.
In the metric system, "mega" is the standard SI prefix for millions, or 10⁶. This makes the megahertz (MHz) a convenient decimal multiple of the hertz (Hz).
In practice, megahertz (MHz) are widely used across large-scale industrial, bulk, and macro-level frequency specifications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Gigahertz?
A gigahertz is a unit of frequency equal to 1,000,000,000 hertz (Hz), the base unit for frequency. Equal to 1,000,000,000 Hz. [2]
The gigahertz is classified as a metric and SI-compatible unit of frequency. Gigahertz can be abbreviated as GHz; for example, 1 gigahertz can be written as 1 GHz.
In the metric system, "giga" is the standard SI prefix for billions, or 10⁹. This makes the gigahertz (GHz) a convenient decimal multiple of the hertz (Hz).
In practice, gigahertz (GHz) are widely used across large-scale industrial, bulk, and macro-level frequency specifications within SI metric workflows, engineering documentation, and technical data sheets.
When converting frequency between megahertz (MHz) and gigahertz (GHz), keep full floating-point precision (1 MHz = 0.001 GHz; 1 GHz = 1,000 MHz) during intermediate calculations and round only the final gigahertz figure to match your instrument tolerance.
