How to Convert Gigahertz to Megahertz

1 gigahertz = 1000 megahertz

Megahertz = Gigahertz × 1000

Example: 42 GHz × 1000 = 42000 MHz

Reverse Conversion

To convert megahertz back to gigahertz:

  • Remember, 1 megahertz equals 0.001 gigahertz.
  • To convert 42000 MHz to GHz, multiply 42000 x 0.001, resulting in 42 GHz.

42 GHz is also equal to:

  • 4.2 × 107 kilohertz
About these units

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

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