PPM to Hz Calculator

Frequency Stability in a crystal oscillator is usually represented in ppm (parts per million). However, it is easier to understand this in terms of frequency. This calculator converts the ppm value of frequency stability to give you the equivalent variation in Hz.

Convert Frequency Stability of a Crystal Oscillator from PPM to Frequency in Hz


  • Frequency Variation
  • Min Frequency
  • Max Frequency

The frequency stability of a crystal oscillator represents the variation in output frequency due to external conditions like temperature variation, voltage variation, output load variation, and frequency aging. Frequency stability is usually represented in ppm (parts per million) or ppb (parts per billion) which can be converted to an equivalent value in Hz. The above equation can be used to convert the frequency stability in ppm to a value in Hz which is easier to understand.
