specific volume[spə′sif·ik ′väl·yəm]
The specific volume of a substance is a physical quantity determined by the ratio of the volume V to the mass m of a body. The specific volume v of a homogeneous substance is given by the formula v = V/m. Specific volume is the inverse of density. The units of specific volume are 1 m3/kg in the International System of Units and 1 cm3/g in the cgs system; 1 m3/kg = 103 cm3/g.
