If I can find the formula would it be possible?

Here is the current standard for the calculation: http://www.teos-10.org/software.htm

But that is probably 100x more complicated needed. I would just use a lookup table or a simple linear plot between two data points in the table near your target range.

I cannot find a function in that to convert conductivity to SG. Can you be more specific what I'm looking for?

You are looking for Specific Volume. SV is the inverse of SG: SG = 1/SV

Have not had enough time. Honestly would not get hopes up for it.
