How to convert nepers to decibel (power)s
Convert through a plain ratio: neper → ratio → decibel (power). Logarithmic units cannot be converted by multiplying alone.
Neper: The natural-log counterpart to the decibel. 1 Np ≈ 8.686 dB (amplitude).
Decibel (power): Ten times the base-10 log of a power ratio. 3 dB is roughly double the power.
