Explanation by: Admin
Specific Gravity does not have any unit of measurement Specific Gravity = Density of body/ Density of water at 4°C It is the ratio between the density of an object and a reference substance. Based on the value of specific gravity , we can tell whether the object will sink or float in our reference substance.
