sci.mineral-density-specific-gravity Calculator
Calculates mineral specific gravity and density from mass and volume measurements for identification. Specific gravity: quartz = 2.65; pyrite (fool's gold) = 5.0; galena = 7.5 — density is the simplest screening test for mineral identification.
Inputs
Mass Air G
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
Mass Water G
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
Water Density G Cm3
Mass per unit volume (kg/m³). Water: 1,000. Air: 1.225. Steel: 7,850. Affects buoyancy, flow, and structural loads.
Results
specific gravity (SG)
Reference formula or conversion factor shown for context.
density (g/cm³)
Sample size or count used in the calculation.
volume (cm³)
The computed three-dimensional volume.
closest common mineral
LOS (length of stay) -- the number of days from admission to discharge. A key hospital efficiency metric.
SG = weight in air / weight of displaced water
The computed weight (gravitational force) or mass.
