Megahertz to Kilohertz (MHz to kHz)

Use this calculator to restate a frequency from megahertz in kilohertz. Type the number of MHz, press Convert, and the matching kHz value shows up right away, based on the fixed ratio 1 MHz = 1000 kHz.

About megahertz and kilohertz

Megahertz and kilohertz are both units of frequency, and the megahertz is the larger of the two. A figure given in MHz therefore turns into a bigger number when it is written in kHz, because the units sit at a fixed ratio: 1 MHz = 1000 kHz, which also means 1 kHz = 0.001 MHz.

Using this tool is simple: enter the frequency in megahertz, press the Convert button, and read the result in kilohertz. You can then copy the answer or clear the field to try another value.

MHz to kHz formula

To go from megahertz to kilohertz, multiply the frequency by 1000. In symbols, the frequency f in kilohertz equals the frequency in megahertz times 1000: f(kHz) = f(MHz) × 1000.

For example, converting 3 megahertz works out as 3 × 1000 = 3000 kHz.
