Density is always = mass/volume, or mass per unit volume.  As for what units, that all depends upon what the items are.  The more standard ones, I believe, are kg/cm3 and lbs/in3.  But, there are no "set" units.  It will always be mass/volume.  But, the units can change.

The SI Unit (Standard International) unit for density is

     • kg/ cm^3


     • kg/ mL^3

Although, these units can vary due to what is mass and volume's units because of the density formula.

     D = M/ V
