Hertz to Gigahertz Converter

One Hertz equals 1.000000e-9 Gigahertz (1 Hz = 1.000000e-9 GHz). Multiply a Hertz value by 1.000000e-9 to get the equivalent in Gigahertz. The calculator is above; the formula and worked examples are below.

Formula

GHz = Hz × 1.000000e-9

How to Convert Manually

Use these steps to convert Hertz values to Gigahertz without the calculator.

  1. Write down the value in Hertz (Hz) that you want to convert.
  2. Multiply that value by 1.000000e-9.
  3. For example, 10 Hertz × 1.000000e-9 = 1.000000e-8 Gigahertz.
  4. Label the result as Gigahertz (GHz).

About Hertz and Gigahertz

The hertz is the SI derived unit of frequency: one cycle per second, named after Heinrich Hertz. Sound pitch, mains electricity (50/60 Hz), and display refresh all measure in hertz. The gigahertz is one billion hertz. Modern CPU clock speeds, Wi-Fi bands (2.4/5/6 GHz), and mobile networks operate in gigahertz. One Hertz equals 1.000000e-9 Gigahertz (1 Hz = 1.000000e-9 GHz). Hertz is used in audio pitch and tuning and in mains power frequency. Gigahertz is used in CPU clock speeds.

Precision and Rounding:Frequency conversions are exact decimal shifts except rpm and rps, which involve the factor 60. Audio and radio work round to convenient figures; clock signals, tuning, and rotating machinery balancing need the unrounded value.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
