About Picometre squared
The picometre squared (pm²) equals 10⁻²⁴ m², used in molecular simulation and crystallography for the intrinsic permeability of dense crystalline solids. Halite and anhydrite crystal lattices have calculated matrix permeabilities below 1 pm²; theoretical studies of gas diffusion through graphene oxide membranes work at this scale. 1 pm² = 10⁻⁶ nm² = 10⁻²⁴ m².
About Millimetre squared
The millimetre squared (mm²) equals 10⁻⁶ m² ≈ 1.013 × 10⁹ D, representing extremely high permeabilities beyond the range of most geological materials. It appears in geotechnical research for open rock fractures, coarse gravel channel beds, and large-cell open-foam engineered materials. 1 mm² = 10⁶ µm² = 10⁻⁶ m².
