Archimedes' principle is used in a lactometer to measure the specific gravity (density) of milk. The principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. By placing the lactometer in milk, the volume of milk displaced by the lactometer can be measured, which allows for the specific gravity of the milk to be calculated.
The principle of specific gravity, based on Archimedes' principle, is used in various industries to determine the purity or concentration of substances. For example, in the pharmaceutical industry, it is used to measure the concentration of active ingredients in solutions. In the field of materials science, it is used to assess the density and quality of materials like metals and polymers.
Archimedes is credited with discovering the principle of buoyancy, known as Archimedes' principle. This principle states that the upward buoyant force on an object immersed in a fluid is equal to the weight of the fluid that the object displaces.
Archimedes' principle states that a body partially or fully immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces. This principle is used to explain the buoyancy of objects in fluids, such as why objects float or sink in water. Archimedes, an ancient Greek mathematician, is credited with discovering this principle.

Archimedes, a Greek mathematician and inventor, is credited with discovering the principle of buoyancy. He made this discovery while in a bath, noting the water displacement when he got in. This principle is known as Archimedes' principle.
