Sorry, I’ve little bit misinformed you. I used that formula to convert from linear units to ratio (how many times backscatter is weaker than initial signal). I did 1/linear units.
For db I used a little bit more complicated formula to convert it to the ratio mentioned above
=10^(ABS(Value in db)/10)
I believe that this formula is good, but the results are slightly different from 1/linear units.
In any case I would like to use linear units which SNAP provides. It looks easier than tricky works wiht dBs.
