Frequency is the number of cycles per second, measured in hertz (Hz). It describes how fast an AC signal oscillates, how fast a motor spins, or how rapidly a clock ticks.
Converting between Hz, kHz, MHz, GHz and RPM matters when reading a signal on an oscilloscope (Hz/kHz), specifying a radio frequency (MHz/GHz), or relating a motor's RPM to its electrical frequency (f = RPM/60 for a single-pole machine).
Common applications
Reading a signal's frequency; specifying a radio carrier in MHz; converting a motor's RPM to electrical frequency; comparing clock speeds in GHz.
Frequently asked questions
Frequency is the number of cycles per second, measured in hertz (Hz).
f (Hz) = RPM / 60 (for one electrical cycle per revolution).
1 kHz = 1000 Hz.
