How to use
- Enter a value in the Megahertz field.
- The Gigahertz figure appears immediately — no button to press.
- Typing in the Gigahertz field converts back to Megahertz the same way.
- Use the reference table for the values that come up most often.
Megahertz to Gigahertz formula
To convert megahertz to gigahertz, multiply by 0.001.
GHz = MHz × 0.001
Put another way, one megahertz is exactly 1/1,000 of a gigahertz.
Why this factor: the megahertz and the gigahertz are both defined against the hertz, so dividing one definition by the other gives 0.001 directly. Both definitions are set out in full below.
To go the other way, divide by 0.001 — or use the Gigahertz to Megahertz converter, which is the same calculation reversed.
Worked example
Given 60 MHz, multiplying by 0.001 yields 0.06 GHz.
60 MHz × 0.001 = 0.06 GHz
The converter above does this for any value you type, in either direction.
What is a megahertz?
A megahertz is one million cycles per second.
Definition: Exactly 1×10⁶ hertz.
Where it is used: FM radio and broadcast bands, memory clock speeds, and radio communications.
What is a gigahertz?
A gigahertz is one billion cycles per second — the scale of modern processors and wireless.
Definition: Exactly 1×10⁹ hertz.
Where it is used: CPU clock speeds, Wi-Fi bands (2.4 and 5 GHz), mobile networks, and radar.
Megahertz vs Gigahertz
The megahertz and the gigahertz belong to the same family of units, so converting between them is usually a matter of shifting a decimal point or applying a small whole-number factor.
Frequently asked questions
