How to calculate the proportion Specific gravity refers to the proportion of an object under certain conditions, that is, the ratio of the weight of an object per unit volume to the weight of a reference substance. Specific gravity is a quantity closely related to density, but the two are not exactly the same. Specific gravity is often used to determine the purity and quality of a specific substance and has applications in different experiments and industrial production.
