Void ratio to dry density
Type a value in e to get it in g/cm³ instantly.
0.06463g/cm³
That's 1.22× as open as peat — nothing on our list beats it. A cubic meter of it could hold about 975.6 liters of water.
What it means
How much space is in it?
Densities assume a grain density of 2.65 g/cm³, which suits quartz sands and most soils but not iron ores or organic soils.
The math
How to convert e to g/cm³
Porosity and void ratio measure the same voids against different denominators: e = n ÷ (1 − n) and n = e ÷ (1 + e), with n as a fraction.
Example: 40 e = 0.0646341 g/cm³.
