The differences in intermolecular interactions, the density of substance can change at different rates compared to the density of water, that's why the specific gravity also changes with changing pressure and temperature. When using the SI or metric system, in order to calculate volume, mass is divided by the specific gravity or density; and, vice versa, to obtain mass, volume is multiplied by the specific gravity or density. The Gr, Posted 9 years ago. WebAnswer (1 of 19): You cant, because the kilogram is a unit of mass (the amount of material of which an object is made) while the liter is a unit of volume (a part of space). According to google the specific gravity of a human body is 1.01 so technically we should sink in water. The SI units of density are kilograms per cubic meter \(\left( \text{kg/m}^3 \right)\), since the \(\text{kg}\) and the \(\text{m}\) are the SI units for mass and length respectively. The SI unit of density is kg/m^3. Specific volume may be calculated or measured for any state of matter, but it is most often used in calculations involving gases. By comparing the mass of an object relative to its size, we are studying a property called density. Specific gravity (also referred to as relative density) is the ratio of the density of a material compared to the density of water at 4C4\ \mathrm{\degree C}4C (39.2F39.2\ \mathrm{\degree F}39.2F).
