MHz to GHz converter

1 megahertz equals 0.001 gigahertz. Conversions use GHz = MHz × 0.001

MHz → 0.001 GHz

GHz = MHz × 0.001

Questions

How many gigahertz in 1 megahertz?

Exactly 0.001 GHz. The factor follows from the definitions of both units, not from a measurement, so it is exact.

How do I convert MHz to GHz?

Multiply the megahertz figure by 0.001 — or use the converter above, which updates as you type.

Is MHz to GHz the same as GHz to MHz?

No — they are inverses. One MHz is 0.001 GHz, while one GHz is 1,000 MHz.

What is 1 MHz in GHz?

1 MHz = 0.001 GHz (see the value page for the full arithmetic).
