97.56%

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 %

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 = 97.561 %.
