1 GHz = 1000 MHz
1 Gigahertz (GHz) = 1000 Megahertz (MHz).
If you want to reverse convert, use Megahertz → Gigahertz. 1 MHz = 0.001 GHz. You can also explore the full Frequency converter page for more cross conversions.
Conversion formula
Gigahertz to Megahertz formula: value in MHz = value in GHz × 1000.
Megahertz to Gigahertz formula: value in GHz = value in MHz × 0.001.
How to convert Gigahertz to Megahertz
To convert Gigahertz to Megahertz, multiply the value in GHz by 1000. This gives the result in MHz.
For example, 1 GHz = 1000 MHz and 10 GHz = 10000 MHz.
What is Gigahertz?
Gigahertz (GHz): Used for microwave frequencies and processor clock rates; frequency alone does not determine performance. 1 GHz = 1 000 000 000 Hz.
What is Megahertz?
Megahertz (MHz): Used for radio frequencies and electronic clock rates. 1 MHz = 1 000 000 Hz.
FAQ
How many megahertz are in 1 gigahertz?
There are 1000 MHz in 1 GHz.
Why can conversion results differ slightly?
Check the unit definition and rounding. US and imperial measures can differ; rounding intermediate values can also change the final digits.
How do I convert gigahertz to megahertz?
Multiply the value in GHz by 1000 to get the value in MHz.
