About Frequency Converter
Hertz measures how many times something oscillates per second, and everything else here — kilohertz, megahertz, gigahertz — is just that same count scaled by powers of a thousand. A 2.4 GHz WiFi signal oscillates 2.4 billion times per second; a 440 Hz musical note (concert A) oscillates 440 times per second — the enormous range of scale is why the prefixes exist.
This converter is handy for comparing router or phone specifications, since WiFi and cellular bands are listed in GHz, for understanding CPU clock speeds, or for converting an audio frequency between Hz and kHz when reading equipment specs or sound theory.
Because the human ear roughly hears between 20 Hz and 20,000 Hz (20 kHz), any audio-related figure in the megahertz or gigahertz range is describing something other than audible sound, such as a radio carrier wave rather than the sound itself.
