Frequency Converter
Frequency is the number of times a repeating event happens per unit of time. The SI unit is the hertz (Hz), one cycle per second. Rotational speed is often given in revolutions per minute instead; 1 Hz corresponds to 60 RPM.
1 Kilohertz = 0.001 Megahertz
How to convert Kilohertz to Megahertz
One Kilohertz equals 0.001 Megahertz, so multiply any value in kHz by 0.001 to get MHz. To convert back, divide by 0.001 — or multiply by 1,000.
MHz = kHz × 0.001
Example: 25 kHz × 0.001 = 0.025 MHz.
