Ghz to Mhz Converter
Convert gigahertz to megahertz easily. Free frequency converter for computing.
Formula
MHz = GHz × 1000
Common Conversions
How to Convert GHz to MHz
1 GHz = 1,000 MHz. Multiply GHz by 1,000 (or move decimal three places right) to get MHz. So 3 GHz = 3,000 MHz. Used when working with sub-GHz precision in CPU spec sheets, radio frequencies, or signal analysis.
A 3.5 GHz processor base clock = 3,500 MHz. A 5G millimetre-wave band at 28 GHz = 28,000 MHz. Wi-Fi 6E band 6 GHz = 6,000 MHz. Older equipment specifications often show frequencies in MHz; converting from modern GHz makes comparisons easier.
Common GHz to MHz
| GHz | MHz |
|---|---|
| 0.5 GHz | 500 |
| 1 GHz | 1,000 |
| 1.5 GHz | 1,500 |
| 2.4 GHz (Wi-Fi) | 2,400 |
| 3 GHz | 3,000 |
| 5 GHz (Wi-Fi) | 5,000 |
| 10 GHz | 10,000 |
| 28 GHz (5G mmW) | 28,000 |
Frequently Asked Questions
What's a typical CPU clock?
Mobile (phone/laptop): 2.5-3.5 GHz base. Desktop: 3.5-5 GHz. Server: 2.5-3.5 GHz × many cores. 'Boost clock' (turbo) goes higher temporarily; 'base clock' is sustained. Both numbers usually quoted in spec sheets.
Is higher MHz/GHz always faster?
For one core, yes. For multi-core CPUs, more cores at slightly lower clock often outperform fewer cores at higher clock for parallel work. Real-world performance also depends on cache, instruction efficiency, and power management - the GHz number is just one factor.
