What is relative density and its SI unit

However, some possible answers include ice, dust.It doesnot have any si unit.Si unit of relative density is the kilograms per cubic meter.It is a ratio and thus has no units.Relative density of a substance = density of the substance/density of water at 4°c as relative density is the ratio of densities, it has no units.

The si unit of relative density is g/ m3.How does numerical value and unit of mass density compare with relative density?The relative density or specific density is the ratio of density of a substance with respect to the density of water at 40 c.One may also ask, what is the si unit of relative density?What is relative density in physics?

Density is defined as mass per unit volume;The si unit of density is the kilogram.While for a hollow body, density of body is lesser than that of substance.Since the units for both the numerator and denominator in the ratio are same, they cancel each other.Thus relative density has no units.
