   1. The problem statement, all variables and given/known data
   I have a quantity in Rayleighs and need to convert it to dB.
   
   2. Relevant equations
   Intensity Reflection Coefficient R=5.625 x 10^-1 Rayls. dB?
   
   3. The attempt at a solution
   None so far-please advise.
   Thanks.

   Try google here. There is no obvious connection between rayleighs and dB.

   Thanks- already tried that. Also have instructor notes so I see how to handle it, but not why.

   It would also help if you posted the text of whatever problem you are trying to solve.

   The Rayleigh is a unit related to light flux: http://en.wikipedia.org/wiki/Rayleigh_(unit)
   
   dB is a relative measure. Maybe they are asking for dB above 1R in this context?
