The density of water is 1.0 g/mL at room temperature, so the specific gravity is equal to the density of the object expressed without a unit. When substances dissolve in water, the density of the solution is usually different from pure water.

- 1.8: Density and Specific Gravity
specific gravity, ratio of the density of a substance to that of a standard substance. The usual standard of comparison for solids and liquids is water at 4 °C (39.2 °F), which has a density of 1.0 kg per litre (62.4 pounds per cubic foot).
21 Νοε 2023 · The formula for specific gravity, given that the reference substance is water, is the density of the object divided by the density of the water. Here, we use the Greek symbol Rho to indicate...
Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density of water, \[\text{specific gravity} = \dfrac{\text{Density of a substance}(\cancel{g/mL})}{\text{Density of the water at the same temperature}(\cancel{g/mL})}\]
25 Ιαν 2020 · Specific gravity, often abbreviated as GE or SG, is a measurement that compares the density of a substance to the density of water at a specific temperature and pressure. In other words, specific gravity tells us how much denser or less dense a material is compared to water.
10 Ιαν 2018 · 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 used to represent density.) That can be determined using the following formula: SG = ρi ÷ ρr = ρi / ρr.
15 Ιαν 2020 · Specific gravity is the ratio of the density of a substance to the density of a reference substance, which is usually water for liquids and air for gases. When water is used, it is at its highest density, which is at 4 °C or 39.2 °F.
