How to Convert Gigahertz to Hertz

1 gigahertz = 1 × 109 hertz

Hertz = Gigahertz × 1 × 109

Example: 90 GHz × 1 × 109 = 9 × 1010 Hz

Reverse Conversion

To convert hertz back to gigahertz:

  • Remember, 1 hertz equals 1 × 10-9 gigahertz.
  • To convert 9 × 1010 Hz to GHz, multiply 9 × 1010 x 1 × 10-9, resulting in 90 GHz.

90 GHz is also equal to:

About these units

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

Hertz: SI unit of frequency; one cycle (or event) per second. Symbol: Hz = s⁻¹
