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.

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.

The difference between density, specific weight, and specific gravity. Including formulas, definitions, and reference values for common substances.

Specific gravity is determined by dividing the density of a material by the density of water at 4 degrees Celsius. For the calculation, the density of the material and that of the water must be expressed in …

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 to …

Nov 10, 2025 · Specific gravity is a simple measurement that provides a quick way to gauge how heavy a substance is compared to a standard reference material, most commonly water. It is a fundamental …

Jul 23, 2025 · Relative gravity or Specific gravity can be defined as the density ratio of a substance to that of water at a specific temperature. Therefore, Specific gravity tells us if an object will sink or float.

Use this specific gravity calculator to find the specific gravity of different materials and see whether they will float or sink.

Jun 9, 2025 · The specific gravity of a substance is the ratio of its density to a specified reference substance. This ratio is a pure number, containing no units. If the specific gravity ratio for a given …

Specific gravity is the ratio of the density of a substance to the density of water at 4°C. It is a dimensionless quantity, often used to compare how heavy or light a substance is relative to water.
