Common density values

Hi everyone,

This may seem an odd question, but what kind of density values do you consider for materials in Farseer? As a 2D physics engine, Farseer uses area density instead of volumetric density, and while it is relatively easy to get area density values for common thin materials like sheets of paper, I find it's not that easy to get common values for materials like water, wood, etc.

Do you use any kind of heuristic for converting volumetric density into area density? In physics this is highly dependent on object shape, but even in the case of a cube you can't just take the Z dimension to zero, or else the density itself becomes zero. How would you do it for water, for example?

Cheers and thanks in advance for the help!
