Difference Between Density and Specific Gravity - Introduction Whenever we do some work experiment with water or any liquid, we observe that some objects are immersed in water whereas some float over it. For example, ice cubes float on water. Because ice
Density is defined as mass per unit of volume. The specific gravity (SG) or relative density of a substance is defined as the ratio of the weight of the substance to the weight of an equal volume of fresh water. If the volume of one cubic meter is considered, then the SG or rel...

of a substance, and there are also a number of factors that can affect the density of a sample. If the exact composition of a non-homogeneous material is known, its solid density (rs) can be determined using the mass and density of each of the n components using the following equation:...
Substituting for W obj and F B , the equation becomes F net, obj = ( obj ·V obj · g) – ( fluid · V fluid · g) An object that sinks experiences a net downward force where its weight is greater than the buoyant force. Hence, an object whose density is greater than that of...
Specific gravity values aren't very useful except for predicting whether or not something will float on water and for comparing whether one material is more or less dense than another. However, because the density of pure water is so close to 1 (0.9976 grams per cubic centimeter), specific ...
Specific gravity is the ratio of the mass of a volume of a substance to the mass of an equal volume of some substance taken as a standard. For convenience, the general standard used for water is 39.2F and 60F; and for gases, the standard is dried air at the same temperature and ...
