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.

In summary, while both relative density and specific gravity provide information about the density of a substance, specific gravity is a more specific measurement that takes into account the temperature …

Jan 2, 2024 · Relative density measures how dense a substance is compared to another reference substance, often water. Specific gravity is a special case of relative density, where the reference …

Jun 9, 2025 · Density is almost identical to specific gravity, but not quite. Here's how they differ and how to compare them to one another.

In physics, the concept of relative density is also referred to as specific gravity. The relative density formula provides an easy way to compare densities: Here, “ρ” (rho) denotes density, and the …

Apr 12, 2025 · Relative density is the ratio of the density of a substance to the density of a reference material. Specific gravity, on the other hand, is the ratio of the density of a substance to the density …

Relative density is essentially the same as specific gravity, however the temperature used for the water (or even another material) is not necessarily 4 oC. For this reason, a relative density measurement …

Specific gravity (SG), also known as relative density, is the ratio of the density of a substance to the density of a reference substance. For liquids and solids, the reference substance is almost always …

Specific gravity is determined by dividing the density of a material by the density of an equal volume of water using the same units. The units therefore cancel each other out. This means you don't have to …

Specific gravity, which is also called relative density, is a measure of density with respect to the density of pure water. There are many properties of water, such as conductivity of water and many more. If a …
