Gigahertz (GHz)
A gigahertz is 10⁹ Hz. Processor clocks run at 2–6 GHz, Wi-Fi at 2.4, 5 and 6 GHz, and 5G and radar up to tens of GHz.
Symbol: GHz
Quantity: frequency and rotational speed
SI relation: 1 GHz = 1000000000 Hz (exact)
Derivation: 1 GHz = 10⁹ Hz.
Exact: yes, by definition
Typical uses
- CPU and GPU clock speeds
- Wi-Fi, Bluetooth and 5G
- Microwave ovens (2.45 GHz) and radar
