Can anyone help me out with how nucleus calculates mass and how this figure relates to real world mass of a cloth garment?

The nucleus white paper states that "in terms of physics, the mass does not need to be in the real world units for proper collisions as long as the relative values are the same"

and

"there are two factors that make mass setermination more complex: air resistance and point density"

So point density I understand to be the ratio between number of faces and number of CVs.

We can easily work out the surface area of a mesh, so given a known mass of cloth, can we translate this into an "nMass"?
