About Foot squared
The square foot (ft²) equals (0.3048 m)² = 9.290 304 × 10⁻² m² ≈ 9.41 × 10¹³ D. An imperial area unit included for unit-conversion completeness; it occasionally appears in US geotechnical reports where flow cross-sections are expressed in square feet. 1 ft² = 144 in² = 9.290 304 × 10⁻² 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.
