Specific gravity is dimensionless (i.e., has no units). The bulk density of a rock is ρ B = WG / VB, where WG is the weight of grains (sedimentary rocks) or crystals (igneous and metamorphic rocks) and natural …
Difference Between Density and Specific Gravity
Specific gravity values aren't very useful except for predicting whether or not something will float on water and for comparing whether one material is more or less dense than another. However, because the density of pure water is so close to 1 (0.9976 grams per cubic centimeter), specific gravity and density are nearly the same value so long ...

Fluid Properties
The bulk volume can either be the entire rock (containing small pores) or only the non-porous rock. Specific Gravity. Another useful term related to density is the specific gravity ((gamma)). This property is in essence the same as density, but is scaled by some reference density to make value unitless. The definition of specific gravity is ...
Standard Test Method For Specific Gravity And Absorption of Rock …
The specific gravity may be expressed as bulk specific gravity or apparent specific gravity. Bulk specific gravity and absorption are based on a 24 ± 4-h soaking time for the rock specimens tested. This test is appropriate for breakwater stone, armor stone, riprap, and gabion sized rock materials.

Density & specific gravity | Some Meteorite Information
Just as useful as density, however, is the specific gravity. Specific gravity is the ratio of the mass (weight) of a rock to the mass of the same volume of water. Water has a density of 1.0 g/cm 3, so the numeric value of specific gravity for a rock is the same as that for density. Because specific gravity is a ratio, it has no unit. Specific ...

MINERAL PROPERTIES: SPECIFIC GRAVITY
The specific gravity of a mineral determines how heavy it is by its relative weight to water. The specific gravity value is expressed upon how much greater the weight of the mineral is to an equal amount of water. Water has a specific gravity of 1.0. If a mineral has a specific gravity of 2.7, it is 2.7 times heavier than water.
