About these units
Hertz (Hz)
- Definition
- The hertz (Hz) is the SI unit of frequency, equal to one cycle or event per second.
- History
- Named after Heinrich Hertz, who demonstrated electromagnetic waves; adopted by the SI in 1960.
- Current use
- Hertz measures sound, alternating current, and wave frequencies everywhere.
Kilohertz (kHz)
- Definition
- A kilohertz (kHz) is 1,000 hertz.
- History
- It is a metric multiple of the hertz.
- Current use
- Kilohertz describe audio sampling and AM radio frequencies.
