Soil phase diagram calculator
Enter the bulk density, moisture content and specific gravity of a soil to see its solids, water and air drawn to scale, with the void ratio, porosity, degree of saturation and densities.
Works in metric or imperial units.

Questions students ask
How do you calculate void ratio?
e = Gs ρw / ρd − 1, where ρd is the dry density and ρw the density of water.
What is degree of saturation?
The share of the voids filled with water: S = wGs / e.
