Common Conversions
How to Convert MHz to GHz
1 GHz = 1,000 MHz. Divide MHz by 1,000 (or move decimal three places left) to get GHz. So 3,000 MHz = 3 GHz. Used in computer processor clock speeds, radio frequencies, wireless networks.
Reference frequencies: AM radio 0.535-1.605 MHz. FM radio 87.5-108 MHz. Wi-Fi: 2.4 GHz (2,400 MHz) and 5 GHz (5,000 MHz). 5G mobile: 600 MHz to 39 GHz. Modern CPUs: 1.5-5.5 GHz (1,500-5,500 MHz). 1990s CPUs: 100-500 MHz (0.1-0.5 GHz).
Common MHz to GHz
| MHz | GHz |
|---|---|
| 100 MHz | 0.1 GHz |
| 500 MHz | 0.5 GHz |
| 1,000 MHz | 1 GHz |
| 1,500 MHz | 1.5 GHz |
| 2,400 MHz (Wi-Fi 2.4) | 2.4 GHz |
| 3,000 MHz (modern CPU base) | 3 GHz |
| 5,000 MHz (Wi-Fi 5) | 5 GHz |
| 6,000 MHz (Wi-Fi 6E) | 6 GHz |
Frequently Asked Questions
What's the difference between 2.4 GHz and 5 GHz Wi-Fi?
2.4 GHz: longer range (penetrates walls better), more crowded (microwaves, baby monitors), slower max speed. 5 GHz: shorter range, less interference, faster (up to 1+ Gbps). Modern routers offer both bands; devices choose automatically. 6 GHz (Wi-Fi 6E) is even faster but very new.
Is faster CPU GHz always better?
Not always. Modern CPUs trade off: more cores at lower GHz often outperform single-core at higher GHz for parallel work. Mobile CPUs: 2.5-3 GHz is typical, optimised for power efficiency. Desktop: 4-5 GHz, prioritising speed. Server: 2-3.5 GHz × many cores, prioritising throughput.
