How to convert decibel (power)s to stop (photographic)s

Convert through a plain ratio: decibel (power) → ratio → stop (photographic). 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.

Stop (photographic): One stop doubles the light. Identical arithmetic to the octave.
