6 Best Free Online PPM to Hz Calculator Websites

Here is a list of the best free online PPM to Hz Calculator websites. PPM is short for Parts Per Million where Hz is Hertz. Both terms are used to measure the frequency. PPM is often used to specify the frequency in a crystal oscillator. PPB (Parts Per Billion) is also used for high-quality crystal ovens. But Hertz is a common term and thus easy to understand in terms of frequency. You can use the following formula for PPM to Hz conversion:

Frequency difference (Hz) = PPM x Reference frequency / 1,000,000

Alternatively, you can use an online tool to do the same more quickly and accurately. This post covers 6 free websites where you can convert stability frequency from PPM to Hz. All these websites offer simple conversion calculators where you have to provide the PPM and reference Frequency. From that, the calculators give you the converted frequency in Hz.

My Favorite Online PPM to Hz Calculator

As all these calculators are based on the same formula, there are not any measure differences among them. I prefer SiTime.com as it has a nice and clean layout and calculates freeway various along with Max-Min Period. And, it also offers another calculator to convert Hz to PPM.

You can check out our other lists of the best free online RLC Resonant Frequency Calculator websites, online Resistivity Calculator websites, and online Log Graphing Calculator services.

SiTime.com

SiTime.com has a free online conversion calculator to calculate PPM to Hz. The web page starts with a brief explanation of the term followed by the formula. Below that you get the actual calculator. The calculator has two input fields for Frequency and PPM. You can add the values and run the calculation. The results get you Variation, Min Frequency, Max Frequency, and Max-Min Period. This way, you can use this calculator to convert PPM frequency to Hz.

Highlights:

• This calculator finds Min Frequency, Max Frequency, Max-Min Period, and Variation.
• It briefly explains the term with the help of the formula used.
• It also offers another calculator to convert Hz to PPM.

5G-Tools.com

5G-Tools.com offers a PPM to Hz Converter that you can use to convert the PPM to Hz and vice versa. The conversion calculator has a neat interface with an option to select the conversion type at the top. You can pick the “PPM to Hz” mode from there. After that, you can add your input data. This includes the Central Frequency (in MHz) and PPM. With that, you can run the calculation. This gets you the Delta Frequency, Minimum Frequency, and Maximum Frequency in the results.

Highlights:

• This calculator can convert PPM to Hz and vice versa.
• It also calculates frequency range and variation.

EverythingRF.com

EverythingRF.com is a website with a collection of tools, calculators, and products related to Radio Frequency. It has a free online PPM to Hz Calculator. You can use this calculator to convert the Frequency Stability of a Crystal Oscillator from PPM to Frequency in Hz. To do that, you get a simple interface that asks for the Oscillation Frequency of a Crystal Oscillator and Frequency Stability. You have to select the right unit and then add your input data. Based on that, the calculator gets you the Frequency Variation, Min Frequency, and Max Frequency.

Highlights:

• This calculator calculates Frequency Variation, Min Frequency, and Max Frequency from PPM.
• It also shows the formula for this calculation.

RFWireless-World.com

RFWireless-World.com is a free website where you can calculate PPM to Hz online. It has a simple calculator for this conversion. The calculator does the conversion of the PPM value to Frequency in Hz. To perform the calculation you have to provide two inputs. The first input is RF Carrier Frequency in GHz and the second input is Frequency in PPM. After that, when you run the calculator, it shows the Frequency in Hz. It does not calculate minimum or maximum frequencies or any variation. But it does cover the formula used.

Highlights:

This calculator only gives the frequency (Hz) in the output.

HyperElectronic.net

HyperElectronic.net is another website where you can calculate PPM to Hz online. It offers a simple calculator that calculates frequency range and variation. It lists five sections together with a calculate button at the bottom. You have to add the first two values which include Frequency and PPM. Then you can click the calculate button to get the values of Frequency Variation, Min Frequency, and Max Frequency. Apart from that, the web page also includes the formula of the calculation and provides a brief explanation.

Highlights:

• This calculator calculates Frequency Variation, Min Frequency, and Max Frequency.
• It also covers the formula with a brief explanation.

Changpuak.ch

Changpuak.ch is a free website with a PPM to Hz Converter. It is a simple conversion calculator that can help you convert the frequency stability of a crystal oscillator from Parts Per Million (PPM) to Hertz (Hz). To perform the conversion, you have to add the Center Frequency and Tolerance. You can add the Center Frequency value in GHz, MHz, or kHz. Similarly, you can add the Tolerance in PPM or PPB. Then you can click the Convert button to perform the conversion. This gets you Frequency Variation, Minimum Frequency, and Maximum Frequency.

Highlights:

• This tool converts PPM/PPB to Hz.
• It also calculates frequency range and variation.
