1,000ppm
That's 10× as clean as a good hi-fi amplifier, while the edge of audibility is 5× worse. That is about -60 dB.
Convert the other way: ppm to %
What it means
How clean is that?
A single THD number hides which harmonics are present. Low-order distortion is far less audible than the same amount of high-order.
The math
How to convert % to ppm
To convert percent to parts per million, multiply by 10,000.
Example: 0.1 % × 10,000 = 1,000 ppm.
In the other direction, 1 ppm = 0.0001 %.
