How to convert octaves to stop (photographic)s

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

Octave: A factor of two — in frequency, or in light as a photographic stop.

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