The Free Online Frequency Converter helps you convert one measuring unit of frequency into another measuring unit. You can convert between cycles, degrees, gigahertz, kilohertz, megahertz, radian, revolution, RPM, terahertz, and support many other conversions.

We mainly ask the question, how many times that event happened in a certain period. In other words, we are referring to the frequency.

So in simple words, frequency is defined as the occurrence or repetition of a particular event for a given amount of time.

In physics, **frequency** is the number of waves that pass the fixed point within a unit of time. Or the number of vibrations or the cycles undergo by the body within a unit of time.

The formula to measure the frequency is **f = 1/T **where

**f**= frequency (the Greek letters nu (ν) and omega (ω) are also used to represent the frequency at certain points)**T**= time-period

*So if the object completes its one cycle or the vibration within half a second, its frequency would be 2 per second. And if it completes 100 cycles within a second, then it would be 100 per second.*

The frequency is primarily divided into two types.

- Angular frequency describes the number of revolutions at a fixed or given interval of time.
- Spatial frequency depends on the spatial coordinate and is inversely proportional to the wavelength.

The **SI-derived unit hertz **(named in honor of the German physicist Heinrich Rudolf Hertz)expresses the frequency.

However, the other units like 1/second, cycle/second, degree/hour, degree/minute, degree/second, gigahertz, kilohertz, megahertz, millihertz, radian/hour, radian/minute, radian/second, revolution/hour, revolution/minute, revolution/second, RPM, terahertz, etc., are also used to measure the frequency.

**1 hertz (Hz) = one cycle per second****1 kilohertz (kHz) = 1,000 Hz****1 megahertz (MHz) = 1,000,000 Hz**

The moon orbits the earth once every 27.322 days. Therefore, the moon's frequency to revolve around the earth is slightly more than 12 cycles per year. An **"A"** note on a violin string vibrates at about 440 Hz (440 vibrations/second).

Everything that is in the world vibrates at a specific frequency and wavelength— even your thoughts. The thoughts with positive energy have a different frequency than those with negative energy.

The frequency of the alternative current (AC) in India is 50 Hz. And it varies from country to country. So the electronic products manufactured for India should be made by keeping in mind the AC frequency.

It's also 60 Hz in some countries, so the electronic products should be manufactured following said frequency.

An object transmits the sound when it vibrates. It moves back and forth during vibration and pushes the air in waves. The number of airwaves that hit your ear/second (frequency) determines that sound's pitch.

The sound with more waves/second has a higher pitch than those with fewer waves/second.

The frequency is measured in **SI-derived unit hertz**. However, other measuring units are still used like 1/second, cycle/second, degree/hour, degree/minute, degree/second, gigahertz, kilohertz, megahertz, millihertz, radian/hour, radian/minute, radian/second, revolution/hour, revolution/minute, revolution/second, RPM, terahertz, etc., to measure the frequency.

Moreover, sometimes, you have to convert one measuring unit of frequency into another measuring unit. Here the **online** **frequency unit converter **helps you a lot for accurate and precise conversion.

An online frequency unit converter tool makes the conversion process easy. You can easily convert one measuring unit of the angle to another measuring unit within no time.

To do this, follow the below-mentioned steps.

- Open the
**Online Frequency Unit Converter Tool**. - Enter the amount
**70**in the first column. - In the second column, "Select from," select rpm (revolution/minute) as a measuring unit from which you want to convert.
- In the third column, "Select to," select rps (revolution/second) as a measuring unit in which you want to convert.
- Click on the "convert" button; the result will be 1.1666666667 rps (revolution/second) within no time.

Therefore, 70 rpm (revolution/minute) = 1.1666666667 rps (revolution/second).
