Frequency converter

gigahertz to megahertz

Convert gigahertz (GHz) to megahertz (MHz). Use an editable frequency converter, conversion formula, and reference table.

1,000

1 GHz = 1,000 MHz

Calculated in your browser

Conversion formula

MHz = GHz × 1,000

One gigahertz equals 1,000 megahertz. Multiply your value in gigahertz by this factor to get megahertz. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 gigahertz:
5 × 1,000 = 5,000 MHz

About these measurements

Frequency measures cycles per second.

The base reference used here is the hertz. One gigahertz is 1,000,000,000 base units; one megahertz is 1,000,000 base units.

Important distinctions

Frequency is the reciprocal of period, not angular velocity.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.

Common questions

How do I convert GHz to MHz?

Multiply the quantity in GHz by 1,000. You can also type the value into the converter above.

Can I reverse the conversion?

Yes. Use the swap button or open the megahertz to gigahertz converter.
