Megahertz to Gigahertz Converter MHz → GHz
1 megahertz (MHz) = 0.001 gigahertz (GHz). Type a value below — the conversion happens instantly, entirely on your device.
1 MHz = 0.001 GHz
2400 megahertz = 2.4 gigahertz
2400 × 0.001 = 2.4
1 MHz equals 0.001 GHz, so multiplying by 0.001 converts the value. The result describes the exact same quantity — only the measuring stick changes.
How to convert megahertz to gigahertz
gigahertz = megahertz × 0.001 — multiply the megahertz value by 0.001.
Example: 2400 MHz = 2.4 GHz.
To convert the other way: megahertz = gigahertz ÷ 0.001 — or use the dedicated GHz to MHz converter .
Megahertz to gigahertz divides by 1,000: the 2,400 MHz Wi-Fi band is 2.4 GHz, and a 3,600 MHz CPU is 3.6 GHz. Same quantity, friendlier number.

About the units
What is a megahertz?
A megahertz is 1,000,000 Hz. FM radio, older CPU clocks and RF bands are quoted in MHz.
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.
Frequently asked questions
How many gigahertz are in 1 megahertz?
1 megahertz (MHz) = 0.001 gigahertz (GHz).
What is the formula to convert megahertz to gigahertz?
gigahertz = megahertz × 0.001 — multiply the megahertz value by 0.001.
How do I convert MHz to GHz without a calculator?
Multiply by 0.001 for a close estimate. Exact factor: 1 MHz = 0.001 GHz.
Is this MHz-to-GHz 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.
