Convert Kilohertz to Megahertz

1 kilohertz is 0.001 MHz. One kilohertz is exactly 0.001 megahertz.

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

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 kilohertz to megahertz? The converter and the working

  1. 1.Take the measurement in kilohertz.
  2. 2.Multiply by 0.001 — that is how many megahertz fit in one kilohertz.
  3. 3.To go back the other way, divide by 0.001, or multiply by 1000.

Worked example: 25 kilohertz to megahertz

Formula
kHz × 0.001 = MHz
Arithmetic
25 × 0.001 = 0.03 MHz
Answer
25 kHz = 0.03 MHz

The factor is exact, so this figure is exact too — only the display is rounded.

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.

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.

How many megahertz are in a kilohertz?

One kilohertz is 0.001 megahertz, exactly. Going the other way, one megahertz is 1000 kilohertz. 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.

Every frequency unit here

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 kilohertz.

Questions people actually ask

How many megahertz are in a kilohertz?
0.001. A million hertz. FM radio sits at 88 to 108 MHz, and a processor clock was quoted here until the late 1990s.
How do I convert megahertz back to kilohertz?
Divide by 0.001, or multiply by 1000 — they are the same operation.
