 # Convert ppm to Hz (hertz)

If you’re working with electronic equipment or digital data, you may encounter the need to convert between units of measurement that aren’t necessarily intuitive. One such conversion is between parts per million (ppm) and hertz (Hz).

Approximately to convert ppm to Hz (hertz) can be used the formula:

Let’s define what ppm and Hz are. ppm is the number of millionths of some value. Hz, on the other hand, is a unit of frequency.

So why might you need to know how to convert between ppm and Hz? One common scenario is when working with electronic equipment that measures or produces signals with very precise frequencies. For example, if you’re working with a signal generator that outputs a waveform with a certain ppm deviation from its nominal frequency, you may need to convert that deviation to a frequency offset in Hz.

To convert ppm to Hz, you need to know the central frequency (at Hz or MHz) of the waveform you’re working with. Let’s say the central frequency is 1000 MHz. If the waveform has a ppm deviation of 16, the delta Frequency (frequency offset) will be 15000 Hz (±)

Conversely, if you have a delta Frequency (frequency offset): 15000 Hz (±) and central frequency: 1000 Mhz and want to convert it to ppm, you will get ppm(±): 15.

In conclusion, converting ppm to Hz (or vice versa) is a simple calculation that requires knowledge of the central frequency of the waveform you’re working with. Whether you’re working with electronic equipment, digital data, or other applications that require precise frequency measurements, understanding how to convert between ppm and Hz can help you achieve more accurate results.
