How to use it
- Type the value in the megahertz box.
- Read the result in gigahertz as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
GHz = MHz × 0.001
Multiply the value in megahertz by 0.001 to get gigahertz.
Example
To convert 25 MHz to gigahertz: 25 × 0.001 = 0.025 GHz.

About the units
- Megahertz
- A megahertz is exactly one million hertz, used for FM radio, memory speeds and older processors.
- Gigahertz
- A gigahertz is exactly one billion hertz, used for processor clock speeds, Wi-Fi and 5G bands.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many gigahertz are in one megahertz?
1 MHz = 0.001 GHz exactly.
How do I convert megahertz to gigahertz?
Use GHz = MHz × 0.001. For example, 25 MHz = 0.025 GHz.
How many megahertz are in one gigahertz?
1 GHz = 1,000 MHz.
How many hertz is a 3.5 GHz processor?
3.5 GHz is 3500 MHz or 3.5 billion hertz, so the processor clock ticks 3.5 billion times per second. Clock speed alone does not decide performance; core count and design matter too.
How do I convert BPM to hertz?
Divide beats per minute by 60, so a tempo of 120 BPM is 2 Hz, two beats per second. The same works for heart rate: 72 beats per minute is 1.2 Hz.
