An object's loss of weight in water equals the weight of the volume of water it displaces, making its specific gravity equal to the mass of an object in air divided by its gain of water weight.

Question

Quizplus · Accepted Answer

The specific gravity of an object is actually calculated as the ratio of the mass of the object in air to the loss of weight in water, not the gain. This principle is based on Archimedes' principle, which states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.
