Conversion Formula
pm² = cm² × 1.000000000e+20
About Centimetre squared
The centimetre squared (cm²) equals 10⁻⁴ m² ≈ 1.013 × 10¹¹ D, present in unit-conversion tables as a logical extension of the SI area series. It is effectively beyond the range of any natural porous medium and arises only in theoretical packed-bed studies or large-aperture industrial filter specifications. 1 cm² = 10⁴ mm² = 10⁻⁴ m².
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.
