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 …

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 …

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 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 …

Nov 29, 2025 · Relative density is written as a simple ratio: Since it is a comparison of two similar quantities, there is no unit. Relative density only tells us how many times a material is denser …

May 21, 2024 · Density is a measure of how much mass is present in a given volume of matter. Relative density is the comparison of the density of one material to the density of a particular …
