Calculating Specific Gravity. The following formula is used to calculate the specific gravity of a material. SG = ρ / ρW. Where SG = specific gravity, ρ = density of the material (kg/m 3 ), ρW = density of water ( kg/m 3 ). The reference density of water at 4 o C (39 o F) is used as the reference as these are the conditions of maximum density.

Aug 18, 2016· Specific Gravity. The specific gravity is a measure of whether a mineral is heavy or light. It is a comparison of the weight of a piece of the mineral with the weight of an equal volume of water. The mineral quartz, for example, has a specific gravity of 2.65. This means that a piece of quartz is a little more than 2½ times as heavy as an ...

MINERAL GALLERY - SPECIFIC GRAVITY

Specific Gravity is a measure of the density of a mineral. At times it is such a useful property that it is the only way to distinguish some minerals without laboratory or optical techniques. Gold (pictured) can easily be distinguished from "fool's gold" by specific gravity alone, although there are many other ways.

Calculating Density

Jun 19, 2020· However, specific gravity is a unitless number, and is the same in the metric system or any other measurement system. It is very useful when comparing the density of two objects. Since specific gravity is unitless, it doesn't matter whether the density was measured in g/cm 3 or in some other units (like lbs/ft 3).

The Density of Common Rocks and Minerals

Jan 23, 2020· The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
