What is the difference between specific gravity and density?
What is the difference between specific gravity and density?
Density is defined as mass per unit volume. It has the SI unit kg m-3 or kg/m3 and is an absolute quantity. 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 also called density?
specific gravity, also called relative density, 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).
Why is density called specific gravity?
Usually specific means that the quantity does not depend on how much you consider, if you take 1 L of ethanol or 2 liters – they have the same SG because you need to compare it with the same amont of water and the volume goes away in the ratio.
What is relation between density and specific gravity?
Difference Between Specific Gravity and Density
| Difference Between Density and Specific Gravity | |
|---|---|
| Density | Specific Gravity (Relative Density) |
| It is the mass of an object per unit volume | Relative density is the ratio of a substance’s weight to the weight of the same volume of water. |
What is the difference between density and specific gravity quizlet?
Density is the relations hip of a substance’s mass to its volume and has specific units whereas specific gravity refers to the comparison of a substance’s density with that of water’s and has no specific units.
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.
Can you convert specific gravity to density?
What is specific density means?
Specific density is the ratio of the mass versus the volume of a material.
What is the relationship between density and specific gravity?
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.
