Relative density is the ratio of the density of a substance to the density of water. For Example: The relative density of pure water at 4 °C is 1.

Relative density of a substance is the ratio of its density and a reference material's density. If the reference material is water then relative density is also called as specific gravity.

Relative density of a substance is defined as the ratio between the density of the substance to the density of water at 40C. Relative density is also known as specific gravity. The relative density of a substance is a pure number without any unit. It tells how many times a substance is heavier than water. Relative...

The relative density of a substance is a pure number without any unit. It tells how many times a substance is heavier than water. Relative density (R.D) of a substance can be calculated by dividing density of a substance with the density of water. read less

Relative density, or specific gravity,[1][2] is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. The term "relative density" is often preferred in modern scientific usage. If a substance's relative density is less than one then it is less dense than the reference; if greater than 1 then it is denser than the reference. If the relative density is exactly 1 then the densities are equal; that is, equal volumes of the two substances have the same mass. If the reference material is water then a substance with a relative density (or specific gravity) less than 1 will float in water. For example, an ice cube, with a relative density of about 0.91, will float. A substance with a relative density greater than 1 will sink. Temperature and pressure must be specified for both the sample and the reference. Pressure is nearly always 1 atm equal to 101.325 kPa. Where it is not, it is more usual to specify the density directly. Temperatures for both sample and reference vary from industry to industry. In British brewing practice the specific gravity as specified above is multiplied by 1000.[3] Specific gravity is commonly used in industry as a simple means of obtaining information about the concentration of solutions of various materials such as brines, sugar solutions (syrups, juices, honeys, brewers wort, must, etc.) and acids. read less

Density of any substance with respect to density of water is relative density. If relative density of any substance is less than 1 it will float in water If its more than 1 it will sink. Relative density is also known as specific gravity. Density of water is taken as standard i.e. 1000 kg/ m^3 or...
