The formula
GHz = MHz × 0.001
Worked through with a real value: 10 megahertz = 0.01 gigahertz.
Going the other way: MHz = GHz × 1000, so 1 gigahertz = 1000 megahertz.
What each unit is
- megahertz MHz
- A million hertz, used for FM radio, television, and older computer processors.
- gigahertz GHz
- A billion hertz, the standard measure of modern processor clock speeds.
Where these come from
- 1 megahertz = 1000000 hertz
- 1 gigahertz = 1000000000 hertz
Every other number on this page is computed from those, and each category is pinned to conversions worked out by hand from the units' primary definitions before it ships.
