How to Convert Megahertz to Gigahertz

1 megahertz = 0.001 gigahertz

Gigahertz = Megahertz × 0.001

Example: 20 MHz × 0.001 = 0.02 GHz

Reverse Conversion

To convert gigahertz back to megahertz:

  • Remember, 1 gigahertz equals 1000 megahertz.
  • To convert 0.02 GHz to MHz, multiply 0.02 x 1000, resulting in 20 MHz.

20 MHz is also equal to:

About these units

Megahertz: SI decimal multiple of hertz; 1 MHz = 1,000,000 Hz = 10⁶ Hz

Gigahertz: SI decimal multiple of hertz; 1 GHz = 1,000,000,000 Hz = 10⁹ Hz

Frequently Asked Questions
