Hertz to Kilohertz (Hz to kHz)
Convert hertz to kilohertz: 1 Hz = 0.001 kHz. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.
Formula
1 Hz = 0.001 kHz
kilohertz = hertz × 0.001 — reverse: hertz = kilohertz × 1000
The factor is derived from the SI definitions of both units (base unit: Hz) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.
Worked examples
- 5 Hz = 0.005 kHz
- 12.5 Hz = 0.0125 kHz
- 100 Hz = 0.1 kHz

FAQ
How many kilohertz are in one hertz?
1 Hz = 0.001 kHz. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.
What is the formula to convert hertz to kilohertz?
Multiply the value in hertz by 0.001: kilohertz = hertz × 0.001. For example, 5 Hz = 0.005 kHz.
How do I convert kilohertz back to hertz?
Multiply by the inverse factor 1000 (hertz = kilohertz × 1000), or use the kilohertz-to-hertz page.
