Morphology

kHz = kilohertz (transparent) = kilo + hertz

The symbol 'kHz' is an abbreviation of 'kilohertz', and 'kilohertz' is transparently kilo- + hertz meaning 'thousand hertz'.

Etymology

The word kHz is short for the prefix kilo- and Hz; kilo- means 'thousand', as in kilogram and kilometer, and Hz stands for hertz, named after the scientist Heinrich Hertz and meaning 'cycles per second'. So kHz literally means 'thousand hertz', or a thousand cycles each second.
