Relative density, also called specific gravity, [1][2] is a dimensionless quantity defined as the ratio of the density (mass divided by volume) of a substance to the density of a given reference material.

Relative density (or specific gravity) is the ratio of the density of a substance to the density of water. It tells us whether a substance is heavier or lighter than water.

Jul 23, 2025 · Relative density, also known as specific gravity, is a dimensionless quantity that compares the density of a substance to the density of a reference substance, typically water at 4°C.

Density and relative density are both important concepts in the study of materials and their properties. While density measures the mass per unit volume of a substance, relative density compares the …

Relative density is the ratio of the density of a specific substance to the density of a reference substance, typically water for liquids and solids, and air for gases.

Density is defined as the ratio of the mass and the volume of a body. On the other hand, relative density is defined as the ratio between the density of a body and the density of some other reference body.

Jun 21, 2023 · Relative Density: Relative density, also known as specific gravity, compares the density of a substance to the density of a reference substance, usually water. It is a dimensionless quantity …

May 21, 2024 · Relative density is the comparison of the density of one material to the density of a particular standard, such as water, at a given temperature or pressure. Relative density is also …

Since comparison of density is done with water (referenced substance) the other name of the ratio is specific gravity of a given substance. Because the density of water is 1g/cm³.Relative density has no …

Mar 18, 2019 · Because it is a ratio, relative density or specific gravity is a unitless value. If its value is less than 1, then the substance is less dense than water and would float.
