Convert Hertz to Gigahertz (Hz to GHz)
1 hertz (Hz) = 1 × 10⁻⁹ gigahertz (GHz). 1 GHz = 1000000000 Hz. Example: 15 Hz = 15 × 1 × 10⁻⁹ = 1.5 × 10⁻⁸ GHz.

How to Convert Hertz to Gigahertz
- 1 Hz = 1 × 10⁻⁹ GHz
- 1 GHz = 1000000000 Hz
- Example: convert 15 Hz to GHz: 15 Hz = 15 × 1 × 10⁻⁹ GHz = 1.5 × 10⁻⁸ GHz
Formula
GHz = Hz ÷ 1000000000
Derivation from SI units:
- 1 Hz = 1 s⁻¹, one cycle per second.
- 1 GHz = 10⁹ Hz.
Both units are defined exactly, so the factor is exact. Hertz definition: hertz; Gigahertz definition: gigahertz.
Worked examples
- A reading of 50 Hz converts to 5 × 10⁻⁸ GHz.
50 Hz × 1 × 10⁻⁹ = 5 × 10⁻⁸ GHz - A value of 440 Hz is 4.4 × 10⁻⁷ GHz.
440 Hz × 1 × 10⁻⁹ = 4.4 × 10⁻⁷ GHz

Where it's used
Hertz are used for mains power (50/60 Hz), while gigahertz appear in CPU and GPU clock speeds. Both measure frequency and rotational speed, so the conversion is a fixed factor.
