How to convert decibel (power)s to octaves
Convert through a plain ratio: decibel (power) → ratio → octave. 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.
Octave: A factor of two — in frequency, or in light as a photographic stop.
