Convert

Gigahertz to Megahertz

Exact answer: 1 GHz = 1000 MHz (exact – SI decimal prefix)

Gigahertz and Megahertz both belong to the Frequency family. The difference is a decimal prefix, so the factor is a clean power of ten. Frequency ranges from hertz in electrical engineering through megahertz in radio to revolutions per minute in mechanics.

Examples

010.5 GHz = 500 MHz

Example value from the reference table. Internal calculation uses stored factors; display output is rounded.

02Common mistake

rpm and bpm are events per minute. Hz is events per second.

03Base unit: Hz

1 GHz = 1000000000 Hz. Then the value is converted through the base unit Hz into Megahertz.
