Unless you are writing a chess engine, I don't think that information will be applicable.
Many grandmasters have stated that in positions where pure calculation is not possible, that they evaluate the position (including position, king safety, developement and pawn structure) based on experience, intuition, and comparison to known positions.
There is a rough points system in place to help people determine if they a winning to a certain extent. 1-pawn, 3-minor pieces, 5-rook and 9-queen.
I know many people use an ajusted version of this which I think goes along the lines of 1-pawn, 2.25-knights, 2.5-bishops, 0.5-bishop pair, 5-rook and 9-queen. That may not be it exactly, but it is something along those lines.
Now, I think it would be good if we could come up with a more complicated point system that took into account position, king safety, developement and pawn structure plus the points for material that already has a system. That way we could mathematically calculate the winning side in a game and by how many points. Any suggestions for how many points anything good be worth?
