Megahertz to Kilohertz (MHz to kHz)
Convert megahertz to kilohertz: 1 MHz = 1000 kHz. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.
Formula
1 MHz = 1000 kHz
kilohertz = megahertz × 1000 — reverse: megahertz = kilohertz × 0.001
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 MHz = 5000 kHz
- 12.5 MHz = 12500 kHz
- 100 MHz = 100000 kHz

FAQ
How many kilohertz are in one megahertz?
1 MHz = 1000 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 megahertz to kilohertz?
Multiply the value in megahertz by 1000: kilohertz = megahertz × 1000. For example, 5 MHz = 5000 kHz.
How do I convert kilohertz back to megahertz?
Multiply by the inverse factor 0.001 (megahertz = kilohertz × 0.001), or use the kilohertz-to-megahertz page.
