Every row is Decibel (power) (dB) converted through the ratio, in exact rational arithmetic.
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.
