The specific gravity of cow milk is 1.032 on average, and the specific gravity is related to the solid content in milk. In addition to the relatively large changes in fat content, the other ingredients of milk are basically stable, so the specific gravity can be used as a simple indicator for evaluating the quality of fresh milk.
