How to Convert Hz to MHz and GHz (2026)

Frequency is measured in hertz (Hz), but most real-world values — radio bands, CPU clocks, Wi-Fi channels — are expressed in megahertz (MHz) or gigahertz (GHz). Converting between them is straightforward: every step up the scale is a factor of 1,000. Use the Frequency Converter to do this instantly.

The Conversion Formula

The metric prefix chain is Hz → kHz → MHz → GHz → THz, each 1,000× the previous. To convert upward, divide by 1,000 per step. To convert downward, multiply by 1,000 per step.

• Hz to MHz: divide by 1,000,000 (1 × 10⁶)
• Hz to GHz: divide by 1,000,000,000 (1 × 10⁹)
• MHz to GHz: divide by 1,000
• GHz to MHz: multiply by 1,000

Example: a 2,400,000,000 Hz Wi-Fi signal is 2,400 MHz or 2.4 GHz. A 3.6 GHz CPU clock is 3,600 MHz or 3,600,000,000 Hz.

Why the Units Matter

Engineers and standards bodies pick the unit that keeps numbers human-readable. A 3.6 GHz processor sounds cleaner than 3,600,000,000 Hz, but both are the same thing. When reading datasheets or RF specifications, you may encounter mixed units in the same document — being comfortable moving between them avoids off-by-a-thousand errors that can cause real problems in antenna design or signal filtering.

Use the Frequency Converter to convert any frequency value across Hz, kHz, MHz, GHz, and THz instantly.
