Morphology

megahertz = hertz (transparent) = mega + hertz

The meaning is directly compositional: 'mega-' means one million and 'hertz' is the unit of frequency, so 'megahertz' transparently denotes one million hertz.

Etymology

Megahertz breaks into mega- meaning 'million', as in megabyte, and hertz, named after the scientist Heinrich Hertz. So, megahertz means 'million cycles per second', which is why we use it to talk about radio frequencies and computer speed.
