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

Convert through a plain ratio: stop (photographic) → ratio → decibel (amplitude). Logarithmic units cannot be converted by multiplying alone.

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

Decibel (amplitude): For voltage, pressure and other field quantities. 6 dB is roughly double the amplitude — and the same fourfold change in power.
