Frequency Converter
What is Frequency?
Frequency is the number of times something repeats per unit of time. The SI unit is the hertz (Hz), one cycle per second; its multiples, the kilohertz, megahertz and gigahertz, are used for radio waves and processors.
Engines and rotating machines are measured in revolutions per minute (rpm): 60 rpm equal 1 Hz. Angular speeds are also given in radians or degrees per second.
