Frequency Converter

This tool converts between frequency units using fixed conversion factors, for example, 1 megahertz equals 1,000,000 hertz, and 1 hertz equals 60 revolutions per minute. Enter a value in any supported unit and it's converted to all others using these standard ratios.

Hertz and its multiples (kHz, MHz, GHz) measure cycles per second, used for everything from AC power and radio waves to computer processor clock speeds. RPM (revolutions per minute) is commonly used for rotational speed, such as engine, motor or hard drive spin rates, and converts directly to hertz since both describe repeating cycles.
