Convert gigahertz to megahertz
Converting gigahertz to megahertz is a common frequency task, whether you are checking a recipe, a spec sheet, a travel distance or a homework problem. Since 1 GHz equals 1,000 MHz, the math is a single multiplication — and this page does it for you instantly, with the formula, a table of common values and answers to the questions people ask most.
Exact factor
How to convert gigahertz to megahertz
To convert gigahertz to megahertz, multiply the number of gigahertz by 1,000. For example, 10 GHz × 1,000 = 10,000 MHz.
MHz = GHz × 1,000
- Write down the value in gigahertz you want to convert.
- Multiply it by 1,000 (the exact GHz→MHz factor).
- The result is your value in megahertz. Check it below with the converter or the table.

About these units
Gigahertz (GHz). A gigahertz is one billion cycles per second. Modern processors clock at several GHz, and Wi-Fi, 5G and radar systems operate in the gigahertz range.
Megahertz (MHz). A megahertz is one million cycles per second. FM radio occupies 88–108 MHz, and older CPU clocks, memory buses and shortwave bands are measured in MHz.
