This Specific gravity or Particle Density calculator used to determine the weight of an individual soil particle per unit volume. Specific gravity is commonly expressed in units of grams per cubic centimeter (g/cm³) or tonnes per cubic meter (t/m³) and abbreviated as ρst or Gs.
Formula:
where,
ρst = Specific gravity,
S = Degree of Saturation,
e = void ratio, and
w = net water content by weight
