Specific gravity is a measurement that compares the density of an object to the density of water. It tells you how much heavier or lighter an object is compared to an equal volume of water.
That is the specific gravity of the substance.
density
The number that compares an object's density to the density of water is called specific gravity. It is a unitless quantity representing the ratio of the density of a substance to the density of water.
density is mass divided by volume
When objects are placed in water, they can sink, float, or stay suspended depending on their density and the density of the water. Objects that are denser than water will sink, objects that are less dense will float, and objects with a similar density may stay suspended in the water.
That is the specific gravity of the substance.

density is mass divided by volume
The tool that compares the density of water to that of coolant is called a hydrometer. It measures the specific gravity of a liquid (the ratio of the density of the liquid to the density of water) to determine its concentration or strength.
When objects are placed in water, they can sink, float, or stay suspended depending on their density and the density of the water. Objects that are denser than water will sink, objects that are less dense will float, and objects with a similar density may stay suspended in the water.
"Specific gravity" or "specific density"
Objects float in water if they have a density lower than water, while objects sink if they have a density higher than water. Density is a measure of how much mass per unit volume an object has. This is why objects like wood and plastic, which have lower density than water, tend to float, while objects like metal, which have higher density, tend to sink.
Objects sink in water when their density is greater than the density of water. This means that the weight of the object is greater than the buoyant force exerted by the water, causing it to displace water as it sinks.
If a block of wood floats in water, it means that the density of the wood is less than the density of water. This is because objects with a lower density than water will float, while objects with a higher density will sink.
Objects that float in water have a lower density than water. -anonymous18_K
Objects that are less dense than water will float on it, such as wood, plastic, cork, and ice. Objects that are more dense than water will sink, such as metals like iron and steel, rocks, and most plastics. The buoyancy of an object is determined by its density compared to the density of water.
