What is the specific gravity and density of water?
Density is defined as the mass per unit volume of a substance. Water has a density of 1 kg/l at 4°C. When the specific gravity is defined based on water at 4°C, then the specific gravity is equal to the density of the liquid….4.6. 2 Specific Gravity.

Is specific gravity density?
Density is defined as mass per unit volume. Specific gravity is the ratio of a material’s density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg m-3). It is therefore a relative quantity with no units.
Is specific gravity and density are same?
Density and Specific Gravity are never the same, because Density has units and Specific Gravity is dimensionless, but they are numerically equal when three conditions are met: (1) Density is measured in grams per cubic centimeter, grams per milliliter, or kilograms per liter; (2) Density and Specific Gravity are …
Why do we use specific gravity instead of density?
The term “Specific Gravity” (SG) is used to define the weight or density of a liquid as compared to the density of an equal volume of water at a specified temperature. If the liquid you are comparing has an SG lower than 1 gram/ml, it will float on water. If it has an SG higher than 1 gram/ml, it will sink.

How do I convert specific gravity to density?
Converting a specific gravity into a density is as simple as multiply the SG by the reference density for which it was based. In most cases, this is the density of water, and therefore your multiply the SG by 1 to yield your density in g/cm^3.
What is the difference between specific gravity and bulk density?
Specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance. Bulk density is weight of a unit volume of a material to the same volume of water including voids.
Why is specific gravity related to density?
Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material, often a liquid. If a substance’s relative density is less than one then it is less dense than water and similarly, if greater than 1 then it is denser than water.
