Dec 8, 2025 · Specific gravity, ratio of the density of a substance to that of a standard substance. Solids and liquids are often compared with water at 4 C, which has a density of 1.0 kg per liter.

As discussed, specific gravity is the measure of the density of an object in comparison to the density of water at an exact temperature and pressure. Changes in the pressure and …

Jun 17, 2025 · The meaning of SPECIFIC GRAVITY is the ratio of the density of a substance to the density of some substance (such as pure water) taken as a standard when both densities …

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 …

Specific gravity, also known as relative density, measures the density of a substance compared to the density of water. Specific gravity is related to density, as both are physical properties used …

Jun 9, 2025 · The specific gravity (SG) is a ratio of the density of the substance of interest (ρi) to the density of the reference substance (ρr). (Note: The Greek symbol rho, ρ, is commonly …

SPECIFIC GRAVITY definition: the ratio of the density of any substance to the density of some other substance taken as standard, water being the standard for liquids and solids, and …

Density is the mass per unit volume of a substance and has units (kg/m³), while specific gravity is a unitless ratio of the density of a substance to that of water.

SPECIFIC GRAVITY meaning: 1. the mass of a particular volume of a substance when compared with the mass of an equal volume of…. Learn more.

Feb 17, 2025 · Specific gravity is defined as the ratio of the density of a substance to the density of a reference substance, usually water at 4°C (39°F) for liquids and solids, and air for gases.
