Specific Gravity to Density Calculator:

Enter the values of specific gravity, SG and density of the reference substance, Dr_(g/cm3) to determine the value of Density, D_(g/cm3).

Specific Gravity to Density Formula:

Specific gravity (SG) is a dimensionless quantity that compares the density of a substance to the density of a reference substance, typically water at 4°C (with a density of 1 g/cm³).

It indicates how dense a substance is compared to water. Specific gravity is used in various scientific and engineering fields to understand material properties.

Both the material’s density and the reference substance’s density can vary slightly with temperature. Ideally, the specific gravity should be measured at the same temperature for accurate comparisons.

The object whose specific gravity you want to determine is submerged entirely in the reference liquid (typically water). The denser the object is compared to the reference liquid, the weaker the buoyant force it experiences.

Denser objects displace less of the liquid, resulting in a smaller upward buoyant force. Conversely, less dense objects experience a stronger buoyant force as they displace more liquid.

Density, D_(g/cm3) in grams per cubic centimetre can be calculated by multiplying the specific gravity, SG of the substance by the density of the reference substance, Dr_(g/cm3) in grams per cubic centimetre.

Density, D_(g/cm3) = SG * Dr_(g/cm3)

D_(g/cm3) = density in grams per cubic centimetre, g/cm³.

SG = specific gravity.

Dr_(g/cm3) = density of the reference substance in grams per centimetre, g/cm³ (1 g/cm³).

Specific Gravity to Density Calculation:

1. A liquid has a specific gravity (SG) of 0.85. Calculate the density of the liquid.

Given: SG = 0.85, Dr_(g/cm3) = 1 g/cm³.

Density, D_(g/cm3) = SG * Dr_(g/cm3)

D_(g/cm3) = 0.85 * 1

D_(g/cm3) = 0.85 g/cm³.

2. A substance has a density (D) of 2.5 g/cm³. Calculate the specific gravity of the substance.

Given: D_(g/cm3) = 2.5 g/cm³, Dr_(g/cm3) = 1 g/cm³.

Density, D_(g/cm3) = SG * Dr_(g/cm3)

SG = D_(g/cm3) / Dr_(g/cm3)

SG = 2.5 / 1

SG = 2.5.
