Kilohertz to Megahertz
A kilohertz is 1,000 hertz, used to describe audio sample rates and AM radio broadcast frequencies. A megahertz is one million hertz, used for FM radio frequencies and older CPU clock speeds. 1 kHz equals 0.001 MHz, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to frequency, measured here against frequency's base unit (Hz) — every other frequency unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
MHz = kHz × 0.001
kHz = MHz × 1,000
Worked example: 5 kHz × 0.001 = 0.005 MHz.

Frequently asked
- How many Megahertz in a kilohertz?
- 1 kHz equals 0.001 MHz.
- How do I convert Kilohertz to Megahertz?
- Multiply the value in kHz by 0.001 to get MHz. The converter above does this instantly as you type.
- Is the conversion exact?
- Yes — Kilohertz and Megahertz are both defined by a fixed conversion factor to frequency's base unit (Hz), so the result shown is exact to the precision displayed, not an approximation.
