Specific gravity is a dimensionless unit that defines the ratio between the density of a rock and the density of water at, typically, 4 Celsius. Density is an important characteristic of a rock, since this parameter helps to identify the rock type and its geologic structure. To calculate the rock density you need to divide the mass of the rock by its volume. The latter can be determined by

Specific Gravity Density for mineral oils is more of a variable than anything. However, a high density can help determine the best use for a particular oil. Mineral oils specific gravity is important when dealing with electrical equipment. If the oil has a high density the water present would float to the top, which would decrease the oils effectiveness. The API Gravity is a special form of
Specific gravity is the density of a material relative to water. Since rocksprised of several distinct mineral phases, they do not have a fixed specific gravity. Instead, a rocks bulk density arises as a result of the percentage of all minerals in a sample multiplied by the specific gravity of each. SGS has extensive experience determining these parameters, including
