This routine calculates volumes enclosed by isosurfaces. The algorithm used is approximate. It doesn't calculate subvoxel volumes. It is fairly accurate as long as a substantial fraction of the voxels are 'inside' the volume.

For convenience, mass is specified rather than volume. Volume/mass conversions assume a density of 1.35 g/ml (0.81 Da/A3).

Please note that an earlier version of the docs cited 1.35 Da/A3. This was an error in the documentation only. The program was using the correct value.
