How to Convert Megahertz to Gigahertz

Formula

To convert Megahertz (MHz) to Gigahertz (GHz): multiply by 0.001

Step-by-Step

  1. Start with your value in Megahertz (MHz).
  2. Multiply by 0.001 to perform the conversion.
  3. The result is your value expressed in Gigahertz (GHz).

Conversion Factor

1 MHz = 0.001 GHz

Reverse Factor

1 GHz = 1000 MHz

Worked Example

Convert 25 Megahertz to Gigahertz: 25 MHz = 0.025 GHz

About Megahertz (MHz)

A frequency unit equal to 1,000,000 Hz. Megahertz is the dominant band for FM radio (88–108 MHz), VHF/UHF TV broadcasts, two-way radio, amateur radio bands, cellular baseband frequencies, and older microprocessor clock speeds (early Pentium: 60–200 MHz). Spectrum allocation by regulators (FCC, Ofcom, ETSI) is organized primarily in MHz bands.

About Gigahertz (GHz)

A frequency unit equal to 1,000,000,000 Hz. Gigahertz is the standard unit for modern CPU clock speeds (3–5 GHz), Wi-Fi (2.4, 5, 6 GHz), cellular radio (5G mmWave up to 40 GHz), radar, GPS carrier frequencies (~1.5 GHz), and microwave ovens (2.45 GHz). Semiconductor datasheets, RF network-analyzer traces, and consumer wireless-device spec sheets all use GHz as the default frequency unit.
