### MINERAL GALLERY - SPECIFIC GRAVITY

Specific gravity is a unitless measure, because it is derived from the density of the mineral divided by the density of water and thus all units cancel. However, since water's density equals 1 gram per cubic centimeter (at specific conditions), then a mineral's specific gravity would also correspond to a mineral's density as expressed in grams ...

Learn More### DENSITY UNIT CONVERSION CALCULATOR

Density is the mass of material per unit volume. Specific gravity is a ratio of the mass of a material to the mass of an equal volume of water at 4 o C. Because specific gravity is a ratio, it is a unitless quantity. For example, the specific gravity of water at 4 o C is 1.0 while its density is 1.0 gcm-3. CONVERSION CALCULATORS Convert between ...
