Use the MHz to GHz Converter
MHz to GHz formula and what each symbol means
GHz = MHz × 0.001
| Symbol | Meaning |
|---|---|
| MHz | Megahertz |
| GHz | Gigahertz |
MHz to GHz examples
1 MHz
1 MHz × 0.001 = 0.001 GHz.
10 MHz
10 MHz × 0.001 = 0.01 GHz.
100 MHz
100 MHz × 0.001 = 0.1 GHz.
MHz compared with GHz
One GHz is 1,000 times as large as one MHz, so your number gets smaller when you convert MHz to GHz and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About MHz and GHz
Megahertz (MHz): One million hertz. Gigahertz (GHz): One billion hertz.
Where MHz to GHz conversions are used
Audio and mains electricity use hertz: 50 Hz or 60 Hz mains, 20 Hz to 20 kHz hearing. Radio, Wi-Fi and processors are described in MHz and GHz.
How to calculate MHz to GHz step by step
- Enter the value in MHz (the starting unit).
- Multiply by 0.001, because 1 MHz = 0.001 GHz.
- The product is the value in GHz. To go back, divide by 0.001 or multiply by 1,000.

How to read your MHz to GHz result
Rotational speed in rpm converts to hertz by dividing by 60, so 3,000 rpm is 50 Hz.

Common mistakes when calculating MHz to GHz
- Mixing mHz (milli) with MHz (mega).
- Dividing when you should multiply: from MHz to GHz multiply by 0.001; from GHz to MHz divide by 0.001.
MHz to GHz FAQ
How many GHz are in 1 MHz?
1 MHz equals 0.001 GHz.
How many MHz are in 1 GHz?
1 GHz equals 1,000 MHz.
Is 1 MHz = 0.001 GHz an exact conversion?
The factor is shown rounded to 7 significant figures (0.001). The calculator above uses more digits.
What is a gigahertz (GHz)?
One billion hertz.
How can I estimate MHz to GHz in my head?
One GHz is 1,000 times as large as one MHz, so your number gets smaller when you convert MHz to GHz and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
What is 200 MHz in GHz?
200 MHz = 0.2 GHz (since 200 × 0.001).
What is 3 MHz in GHz?
3 MHz = 0.003 GHz (since 3 × 0.001).
What is 30 MHz in GHz?
30 MHz = 0.03 GHz (since 30 × 0.001).
How many decimals should I keep when converting MHz to GHz?
Match the precision of your original measurement. For example, 0.01 GHz rounds to 0.01 GHz at 3 significant figures; keep more digits only for engineering or scientific work.
