Hz to PPM Calculator

The frequency stability of a crystal oscillator represents the variation in output frequency due to a number of external conditions like temperature variation, voltage variation, output load, frequency aging etc. This variation can be represented in ±Hz or in ppm (parts per million).

Convert Frequency Variation in a Crystal Oscillator from ±Hz to ppm

Result

  • ppm

For example - If a quartz oscillator has an output frequency of 10 MHz (10000000 Hz) and it has a Frequency Stability / Variation of ±50 Hz. This can be represented as 5 ppm.
