How to convert decibel (power)s to nepers

Convert through a plain ratio: decibel (power) → ratio → neper. Logarithmic units cannot be converted by multiplying alone.

Decibel (power): Ten times the base-10 log of a power ratio. 3 dB is roughly double the power.

Neper: The natural-log counterpart to the decibel. 1 Np ≈ 8.686 dB (amplitude).
