# 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.

## Frequently Asked Questions

In frequency, PPM (parts per million) is a unit used to express the difference between two frequencies. It represents the ratio of the difference between the two frequencies to the frequency of the reference signal, multiplied by one million.

PPM (parts per million) is a unit used to express small quantities of a substance in a larger amount. To convert PPM to Hz (Hertz), you need to know the frequency of the reference signal and multiply it by the PPM value divided by one million.

To convert Hz (Hertz) to PPM (parts per million), you need to know the frequency of the reference signal and the frequency of the signal being measured. Then, subtract the frequency of the measured signal from the frequency of the reference signal, divide by the frequency of the reference signal, and multiply by one million.

The number of Hz represented by 1 PPM (parts per million) depends on the frequency of the reference signal. For example, if the reference frequency is 1 GHz (1,000,000,000 Hz), then 1 PPM would be equivalent to 1,000 Hz. However, if the reference frequency is 100 MHz (100,000,000 Hz), then 1 PPM would be equivalent to 100 Hz.
