[Bf-blender-cvs] [ead6d39] master: Units: Make grams base unit for mass

[Andrew Hale]

Hi Sergej,

Just wondering what the reason for changing this is? As the SI unit for
mass is kilograms, I would have thought that having kilograms as the base
unit would be correct.

Thanks for any clarification!
