Convert Megahertz to Kilohertz
1 megahertz is 1,000 kHz. One megahertz is exactly 1000 kilohertz.
One megahertz is 1000 kilohertz. To convert megahertz to kilohertz, multiply by 1000; to go the other way, divide by 1000 or multiply by 0.001. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A million hertz.

| Unit | Value | Exact factor |
|---|---|---|
| hertz | 1,000,000 Hz | × 1,000,000 |
| kilohertz | 1,000 kHz | × 1,000 |
| megahertz (as entered) | 1 MHz | — |
| gigahertz | 0.001 GHz | × 0.001 |
| terahertz | 0.000001 THz | × 0.000001 |
| revolutions per minute | 60,000,000 rpm | × 60,000,000 |
Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert megahertz to kilohertz? The converter and the working
- 1.Take the measurement in megahertz.
- 2.Multiply by 1000 — that is how many kilohertz fit in one megahertz.
- 3.To go back the other way, divide by 1000, or multiply by 0.001.
Worked example: 25 megahertz to kilohertz
- Formula
- MHz × 1000 = kHz
- Arithmetic
- 25 × 1000 = 25,000 kHz
- Answer
- 25 MHz = 25,000 kHz
The factor is exact, so this figure is exact too — only the display is rounded.

What is a megahertz?
A million hertz. FM radio sits at 88 to 108 MHz, and a processor clock was quoted here until the late 1990s.
What is a kilohertz?
A thousand hertz. AM radio is broadcast here — 540 to 1600 kHz — and audio sampling is quoted in it: a CD samples at 44.1 kHz.
How many kilohertz are in a megahertz?
One megahertz is 1000 kilohertz, exactly. Going the other way, one kilohertz is 0.001 megahertz. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.

The whole group — 6 units with their symbols and the size of each one in hertzs — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a megahertz.
