2020-01-16
Sometimes, certain specifications such as those for frequency counters, oscilloscopes, or signal generators, specify accuracies in PPM, parts per million. In some cases, it is useful to know this representation in percentage, especially when defining accuracies.
Below is a quick table look up to show conversions between the two:
| PPM (Parts per million) | Percent (%) |
|---|---|
| 1 | 0.0001 |
| 10 | 0.001 |
| 100 | 0.01 |
| 1000 | 0.1 |
