Rendered to 6 significant figures.
Formula
Formula
GHz = MHz × 0.001
Multiply any value in megahertz by 0.001 to obtain the value in gigahertz.
Worked example
Convert 1000 MHz to GHz.
- 01Start with 1000 MHz.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 GHz.
Result1000 MHz = 1 GHz

FAQ
What is the conversion factor from MHz to GHz?
1 MHz equals 0.001 GHz. To convert, multiply the value in megahertz by 0.001.
How do I convert 1 MHz to GHz?
1 MHz = 0.001 GHz. For any value, multiply by 0.001.
How do I convert GHz back to MHz?
Divide by the same factor — or equivalently, multiply by 1000. So 1 GHz = 1000 MHz.
When would I need to convert megahertz to gigahertz?
Frequency conversions between MHz and GHz are needed in signal and RF engineering, motor and turbomachinery rotational-speed work, vibration and pulse-rate analysis, and control-loop sample-rate specification. Hz dominates electronics and instrumentation; kHz, MHz and GHz cover audio through microwave; rpm and rps dominate mechanical rotational equipment; cycles per minute, second and hour cover slow industrial cyclic processes. Angular frequency (rad/s) and time-period (Hz ↔ seconds) conversions are NOT included — they require either a 2π factor or a reciprocal relationship.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
