How to convert stop (photographic)s to ratios
Convert through a plain ratio: stop (photographic) → ratio → ratio. Logarithmic units cannot be converted by multiplying alone.
Stop (photographic): One stop doubles the light. Identical arithmetic to the octave.
Ratio: The plain multiplier every logarithmic unit here converts through. Read a decibel figure as an encoding of this number.
