# Density vs. Specific Gravity

The main difference between Density and Specific Gravity is that Density is the factor that represents the ratio mass per unit volume, whereas Specific Gravity defines as the density measurement with respect to the measurement of the density of water at a specific temperature, i.e., 4-degree centigrade. ## Key Differences

Density is an absolute quantity; on the flip side, specific gravity is a relative quantity.
Density has dimensions like it is represented by ρ, whereas specific gravity has no dimensions due to the canceling of two same quantities.
Density is defined as the measurement which is obtained by dividing the mass of the substance by the volume; on the flip side, specific gravity is defined as the measurement which is obtained by dividing the density of a substance to the density of the water at a specific temperature, i.e., 4-degree centigrade.
Density is represented by units, whereas specific gravity is not represented by units.
Density is used for local and marketable applications; on the other hand, specific gravity is used to result in the concentration of different solutions.
Density depends upon the temperature and pressure; on the other hand, specific gravity can be precisely measured at 4-degree centigrade.
Density has S.I unit which kg per cubic meter; on the other hand, specific gravity has no units because it is the proportion of two same quantities.

Density is more precisely in measuring the volumetric mass density.
Specific gravity gives the ratio of the densities of different substances that we want to measure at four centigrade.

### Specific Temperature

Density can be found at any temperature.
Specific gravity can only find at 4-degree centigrade because of the Density of the substance in water and water volume is changing by changing the temperature.

### Density vs. Specific Gravity

Density is defined as the factor which shows the measurement of the mass per unit volume; on the other hand, specific gravity is defined as the density measurements with respect to the measurement of the density of water. Density can be calculated by dividing the mass over volume; on the flip side, specific gravity can be calculated by dividing the density of a substance to the density of water.

Density is represented as the absolute quantity; on the other hand, specific gravity is represented as the relative quantity. The unit of density is known as kilogram per meter cube, whereas the specific gravity has no unit. The symbol of density is P, whereas there is no symbol of specific gravity due to it has no unit.

Density factor is used in commercial and domestic applications; on the other hand; specific gravity is used in the industries to find different solution measurements. Density can be expressed as units; on the flip side, specific gravity is always dimensionless.

Density is affected by increasing the temperature; it increases the volume, and the density factor is the start of decreasing; on the flip side, specific gravity is not affected by increasing or decreasing the temperature because it is a ratio of the same quantity.

Density is more precisely in the volumetric mass density; on the other hand, specific gravity gives the ratio of the densities of different substances which we want to measure at four-degree centigrade.

### What is Density?

Density is defined as the factor of dividing the mass per unit volume. The density of a material can be found by taking the proportion of the mass of the material to the volume of the material. S.I.the unit of density is in kilogram per meter cube. It is symbolized by p. It can be transcribed in the form of units.

Density is an absolute quantity. Density is used for local and marketable applications. It is mostly used to find how much a substance is denser. Density is depended upon the temperature and pressure as the temperature increases, the volume for the substance is increased, and the density of the substance decreases as in pressure.

When pressure increases, the volume of a substance is started decreasing, and density is started to increases. Density is more precisely in the finding of volumetric mass density. The best example of the finding of the density of a substance is like this the mass of the substance is 90 kg, and the volume is 90m. So the density of a substance is fined by dividing the mass by volume.

### What is Specific Gravity?

Specific gravity defines as the proportion of a density of a material to the density of water at a specific temperature, i.e., four-degree centigrade. It can be found by dividing the density of substance of which specific gravity is to find out and divide it by density of the substance in the water at 4-degree centigrade.

Specific gravity is dimensionless. There is no unit of specific gravity because the specific gravity is the ratio of two same quantities, so both the unit cancels out with each other. Specific gravity is a relative quantity.

Specific gravity is used in industries to find the concentration of different solutions. Specific gravity does not depend upon the temperature and pressure because when we increase the pressure, the density of a substance is decreased, and the density of the substance in water also decreases relatively. Hence, the value of specific gravity remains constant.

The example of specific gravity is like a substance of density is 60 kg per cubic meter, and the density of the substance in water is 40kg per cubic meter, specific gravity can be obtained by dividing 60 over 40, and the answer is 1.5 with no unit.
