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 Metre squared
The square metre (m²) is the SI coherent unit of permeability (dimension [L²]) and the reference for all other permeability units. Most geological materials have k far below 1 m²; clean coarse gravel: ≈10⁻⁸ m²; shale: 10⁻²²-10⁻¹⁵ m². 1 m² = 10¹² µm² ≈ 1.013 × 10¹² D.
