About this calculator
A frequency converter changes a rate of repetition between hertz, kilohertz, megahertz and gigahertz, plus revolutions per minute and radians per second. Values convert through the hertz (cycles per second).
Frequently asked questions
How many Hz are in a MHz?
One megahertz is 1,000,000 hertz, and one gigahertz is 1,000 megahertz. A 2.4 GHz Wi-Fi signal cycles 2.4 billion times per second.
How do I convert RPM to Hz?
Divide RPM by 60, since hertz is cycles per second. A motor at 3,000 RPM turns at 50 Hz.
What is radians per second?
Angular frequency in rad/s equals 2π times the frequency in hertz. So 1 Hz is about 6.2832 rad/s.
