sci.mineral-specific-gravity Calculator
Calculates mineral specific gravity (SG = ρ_mineral/ρ_water) from weight in air and in water using Archimedes' principle, for mineral identification. Quartz SG = 2.65; pyrite = 5.02; galena = 7.6 — SG is a rapid diagnostic criterion alongside hardness for non-destructive 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.
Results
specific gravity SG
Reference formula or conversion factor shown for context.
density ρ (kg/m³)
Sample size or count used in the calculation.
SG = m_air / (m_air - m_water)
The value at the specified point or condition.
mineral identification
The value at the specified point or condition.
standard SG values
The computed numeric or monetary value.
moisture effect
Reference formula or conversion factor shown for context.
