Specific Gravity is a unitless number because it is the ratio between the density of the material of interest and a standard material (e.g. water). The units cancel out leaving a numerical value only.

What is specific gravity and its unit?

Specific gravity is the density of a substance, divided by the density of water. Since two units of the same type are divided, specific gravity is dimensionless (i.e., no unit).


What is the unit weight of soil with a specific gravity of 2.65?

The unit weight of soil with a specific gravity of 2.65 is 1.8 g/cc.


What is the specific gravity and its unit?

Specific gravity doesn't have units. It's the density relative to water, so specific gravity is effectively just a number.


What unit is used with specific gravity?

The specific gravity of a substance is the ratio of te density of the substance to the density of water. It is, therefore, a unitless measure.


When the specific gravity equal to density?

Specific gravity and density will have the same value when the two substances under investigation have identical densities. Density is an expression of the amount of mass per unit of volume that a substance exhibits. Specific gravity is a comparison of the density of a substance to the density of water.


What is one unit of measure for mass?

Specific gravity I think. Start there.


What is specific gravity of petrol with unit?

737.22 - see http://www.simetric.co.uk/si_liquids.htm The sp. gravity of the petrol(vehicle) is 0.73722 and that of natural petrol is 0,71122 Note that specific gravity has no units.


What is the difference between density amd specific gravity?

Density is defined as the mass per unit volume. Hence its unit is SI system is kg/m3 But specific gravity other wise known as relative density is defined as the ratio of the density of the substance to that of water. So no unit for specific gravity. Density of water is 1000 kg/ m3 Density of mercury is 13,600 kg /m3 Hence specific gravity or relative density of mercury is 13.6


Does specific gravity has units?

- The specific weight is the weight of a known volume of material at a given temperature and pressure; the unit of measure is kN/m3. - But if you think to relative density: Relative density (specific gravity) is the ratio between the density of the material to be tested and the density of water, at a given temperature and pressure; consequently no unit of measure for this ratio.


Why specific gravity increases in case of skimmed milk?

The specific gravity of skimmed milk is greater than that of whole milk because because cream is lighter than milk, thus removing it makes the remaining liquid heavier per unit of volume. As a liquid's weight per unit of volume increases its specific gravity increases.


Is specific gravity depends to p and T?

Your question is unclear. However specific gravity is another term for density. Density is the mass of a substance in a unit of volume. Kilograms per cubic metre for instance


What are the units of measuring density?

density = mass/volume. The unit of density is kg/m3
