Gigahertz to Megahertz Converter GHz → MHz
1 gigahertz (GHz) = 1000 megahertz (MHz). Type a value below — the conversion happens instantly, entirely on your device.
1 GHz = 1000 MHz
5 gigahertz = 5000 megahertz
5 × 1000 = 5000
1 GHz equals 1000 MHz, so multiplying by 1000 converts the value. The result describes the exact same quantity — only the measuring stick changes.
How to convert gigahertz to megahertz
megahertz = gigahertz × 1000 — multiply the gigahertz value by 1000.
Example: 5 GHz = 5000 MHz.
To convert the other way: gigahertz = megahertz ÷ 1000 — or use the dedicated MHz to GHz converter .
Gigahertz to megahertz multiplies by 1,000: 5 GHz Wi-Fi is 5,000 MHz. Handy when a datasheet lists a band edge in MHz but the product is marketed in GHz.

About the units
What is a gigahertz?
A gigahertz is 1,000 MHz — the clock speed of modern processors and the band of Wi-Fi (2.4/5 GHz) and mobile networks.
What is a megahertz?
A megahertz is 1,000,000 Hz. FM radio, older CPU clocks and RF bands are quoted in MHz.
Frequently asked questions
How many megahertz are in 1 gigahertz?
1 gigahertz (GHz) = 1000 megahertz (MHz).
What is the formula to convert gigahertz to megahertz?
megahertz = gigahertz × 1000 — multiply the gigahertz value by 1000.
How do I convert GHz to MHz without a calculator?
Multiply by 1000 for a close estimate. Exact factor: 1 GHz = 1000 MHz.
Is this GHz-to-MHz converter accurate and private?
Yes. It uses the exact internationally defined conversion factors and computes results locally in your browser — your input is never sent to a server, and the page keeps working offline.
