About Converting Megahertz to Gigahertz
Megahertz and Gigahertz both describe how fast something cycles or rotates, and the conversion is a routine part of reading a car tachometer or motor spec sheet against a scientific frequency figure. Specifically: Megahertz is 1000000 hertz units, and gigahertz is 1000000000 hertz units.
Formula
gigahertz = megahertz × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 megahertz equals 1000000 base units, and 1 gigahertz equals 1000000000 base units, so dividing one by the other gives the direct megahertz-to-gigahertz factor of 0.001.
Simple example
1 MHz × 0.001 = 0.001 GHz
1 megahertz = 0.001 gigahertz.
Real-world example
1,000 MHz × 0.001 = 1 GHz
1,000 megahertz = 1 gigahertz.

Frequently asked questions
How many gigahertz are in 1 megahertz?
1 megahertz equals 0.001 gigahertz, using the exact defined conversion factor rather than an estimate.
How do I convert megahertz to gigahertz?
Multiply the megahertz value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert gigahertz back to megahertz?
Use the reverse factor: 1 gigahertz equals 1,000 megahertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a megahertz?
Megahertz (MHz) is a unit of frequency.
What is a gigahertz?
Gigahertz (GHz) is a unit of frequency.
Is the megahertz to gigahertz conversion exact?
Yes. Both megahertz and gigahertz are defined by fixed standards rather than physical artifacts, so the factor of 0.001 used above is exact to as many digits as you choose to display.
