-60dB
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: dB 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 dB
Percent and decibels are the same figure: dB = 20 × log₁₀(% ÷ 100), and back again % = 10^(dB ÷ 20) × 100. Each factor of ten is 20 dB, and each bit of resolution about 6 dB.
Example: 0.1 % = -60 dB.
