Frequency Converter

100% free online Frequency Converter Tool. This conversion tool will convert a frequency value into different measurement units and display a conversion scale related to the converted value. The SI unit for frequency is the hertz (Hz). One hertz is the same as one cycle per second.

Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency to emphasize the contrast to spatial frequency, and ordinary frequency to emphasize the contrast to angular frequency. So if the time it takes for a wave to pass is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.

Frequency is an important parameter used in science and engineering to specify the temporal rate of change observed in oscillatory and periodic phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light.
