Density is defined as amount of matter per unit volume. This means in a given space , how much mass or simply a matter occupy space.
Density is expressed by the formula
ρ = m/V where
ρ is the density
m is the mass
V is the volume
Specific Gravity is a dimensionless quantity. It is the ratio of density of the substance to the density of reference ( water ,air,petrol.. depends on our choice) substance.
Specific gravity is also called relative density and is expressed by the formula:
Specific Gravitysubstance = ρsubstance/ρreference
The reference material could be anything, but the most common reference is pure water.
