Parts per million to percent
Type a value in ppm to get it in % instantly.
1×10⁻⁵%
Nothing on our list is smaller: a reference measurement instrument is 50× worse. That is about -140 dB.
Convert the other way: % to ppm
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 ppm to %
To convert parts per million to percent, multiply by 0.0001.
Example: 0.1 ppm × 0.0001 = 1×10⁻⁵ %.
In the other direction, 1 % = 10,000 ppm.
