Background

Frequency measures cycles per second. Hz is the SI unit. kHz (10³), MHz (10⁶), GHz (10⁹). RPM for rotating machinery.

Electronics and Computing

CPU speeds in GHz (3.5 GHz = 3.5B cycles/s). Radio: kHz (AM) to GHz (Wi-Fi, 5G).

Audio Frequency

Human hearing: 20 Hz – 20 kHz. A4 = 440 Hz, middle C = 261.6 Hz.
