Mega is a million, kilo is a thousand. A megahertz is a thousand kilohertz. Converting from megahertz to kilohertz, from large units to smaller, requires more digits, decimal point moves to the right by three positions, a thousand times more.

Frequencies audible to humans range from 20 Hz to 20 000 Hz (AUDIO). Speech frequencies important for intelligibility in communications range from 300 Hz to 3000 Hz. Radio frequencies can reach up to 300 GHz ( 300 000 MHz ): Medium Frequencies 300 kHz - 3000 kHz, High Frequencies 3 MHz - 30 MHz, Very High Frequencies 30 MHz - 300 MHz, Ultra High Frequencies 300 MHz - 3000 MHz, Super High Frequencies 3 GHz - 30 GHz, Extremely High Frequencies 30 GHz - 300 GHz.

Wavelength (lambda) in metres is 300 divided by frequency in megahertz ( i.e., the speed of light divided by the frequency in hertz ). Wavelength and frequency have an inverse relationship.
