Frequency Converter

The online unit conversion tool, the Frequency Conversion Calculator, is set up to determine the equivalent frequency in various hertz ranges. The frequency range is measured using the SI unit of Herz. This calculator supports several hertz unit ranges: millihertz, hertz, kilohertz, megahertz, gigahertz, and terahertz. Select the input frequency hertz range from the list, enter your input value, and the output will be displayed in the several hertz ranges above. In AC power, frequency Hertz range conversion is frequently utilized. This calculator can determine RPM, revolution, and radian per second measurements.

Units for Measuring Frequency

Hertz, kilohertz, megahertz, gigahertz, terahertz, cycles per second, revolutions per minute, radians per second, and degrees per second are some examples of frequency units.

What is the frequency calculator used for?

You can use our frequency calculator as a period to frequency calculator or a wavelength to frequency calculator because it combines the above calculations.

How can I use it to convert periods to frequencies?

Enter the duration of one wave cycle (period). The calculator will determine the frequency.

If you are aware of the frequency, you can use this calculator to figure out the period.

How do I use it as a calculator to convert wavelength to frequency? (How to convert wavelength to frequency?)

  1. You can either choose the type of wave and its medium from a list in the first field or enter the wave velocity in the second area. It is preconfigured to light in a vacuum by default.
  2. You can enter a wavelength to display the frequency value.
  3. Therefore, you can practically enter any two variables, and the third will appear immediately.

Frequency Converter Calculation Guide

By calculating the number of cycles per unit period from the time it takes for one entire process to complete, this tool will convert a period to an equivalent frequency value.

An updated conversion scale with a range of period-to-frequency conversion values centered around the converted frequency will appear for each new period entered.


The frequency is determined using the following formula:

f = 1 / T

f = Frequency in the symbols
T = Time.
