density is like weight and gravity is what pulls you to the ground density is what determines weight
Specific gravity is the ratio of the density of a substance to the density of a reference substance. Density is a measure of how mass is distributed in a given volume, while specific gravity compares the density of a substance to that of water. In other words, specific gravity is a dimensionless quantity that provides a relative measure of how dense a substance is compared to water.
specific gravity of any substance can be find out only when it will be in liquid or gas medium.Because specific gravity of any liquid equals to ratio of density of that liquid to the density of water and specific gravity of any gas is the ratio of density of that gas to the density of air. cement is solid material(powder form) and so can not be graded on the basis of specific gravity in all conditions.

The specific gravity of a substance is the ratio of its density to the density of a reference substance (usually water). Specific gravity is a dimensionless quantity that allows us to compare the density of different substances without units.
- The specific weight is the weight of a known volume of material at a given temperature and pressure; the unit of measure is kN/m3. - But if you think to relative density: Relative density (specific gravity) is the ratio between the density of the material to be tested and the density of water, at a given temperature and pressure; consequently no unit of measure for this ratio.
Almost, but not quite. 'Specific gravity' is the density of a substancecompared to water.Numerically . . .Specific gravity of a substance = Density of the substance/Density of water.
"Specific gravity" or "specific density"
Specific gravity is a measure of the density of a substance compared to the density of water. As the concentration of solute in a solution increases, the specific gravity of the solution also increases. This is because the presence of solute particles increases the overall density of the solution.
Density is defined as the mass per unit volume. Hence its unit is SI system is kg/m3 But specific gravity other wise known as relative density is defined as the ratio of the density of the substance to that of water. So no unit for specific gravity. Density of water is 1000 kg/ m3 Density of mercury is 13,600 kg /m3 Hence specific gravity or relative density of mercury is 13.6
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.
Specific Gravity.
Specific gravity and density will have the same value when the two substances under investigation have identical densities. Density is an expression of the amount of mass per unit of volume that a substance exhibits. Specific gravity is a comparison of the density of a substance to the density of water.
"Relative gravity" is used more or less as a synonym for density; it bears no direct relation with "gravity" as such. So, you would have to specify, "specific gravity [or density] of what substance"."Relative gravity" is used more or less as a synonym for density; it bears no direct relation with "gravity" as such.
