About Megahertz and Gigahertz
Megahertz (MHz)
A megahertz is 1,000,000 hertz.
Where it's used: FM radio, computer bus speeds, and older processor clocks.
Gigahertz (GHz)
A gigahertz is 1,000,000,000 hertz.
Where it's used: Modern processor speeds, Wi-Fi bands (2.4/5/6 GHz), and radar.

MHz to GHz Formula and Examples
Direct Formula
GHz = MHz × 0.001 Inverse Formula
MHz = GHz × 1000 Mental Math Shortcut
Divide the value by roughly 1000 to quickly estimate the converted result.
Common Megahertz to Gigahertz Calculations
- 5 MHz = 0.005 GHz
- 10 MHz = 0.01 GHz
- 50 MHz = 0.05 GHz
- 100 MHz = 0.1 GHz
- 500 MHz = 0.5 GHz
Precision & Practical Use
For example, 10 MHz = 0.01 GHz — roughly fractional unit measurement.
Results are computed to up to 9 decimal places. Round to the precision of your measuring instrument — for most frequency applications, 2–3 significant figures are plenty.

How to Convert Megahertz to Gigahertz
How many gigahertzes are in one megahertz?
One Megahertz (MHz) equals 0.001 Gigahertz (GHz). To convert megahertzes to gigahertzes, multiply the megahertz value by 0.001.
How do I convert Megahertz to Gigahertz?
Multiply your megahertz value by 0.001 to get the result in Gigahertz: GHz = MHz × 0.001. For example, 5 MHz = 0.005 GHz.
What is the formula for converting MHz to GHz?
The conversion formula is GHz = MHz × 0.001. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
Is there a quick mental estimate for MHz to GHz?
Divide the value by roughly 1000 to quickly estimate the converted result.
