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.
About Inch squared
The square inch (in²) equals (0.0254 m)² = 6.4516 × 10⁻⁴ m² ≈ 6.54 × 10¹¹ D. An imperial area unit included for unit-conversion completeness; it appears in some US oil-country tubular goods and industrial filter-media specifications where flow cross-sections are stated in square inches. 1 in² ≈ 6.452 cm² = 6.4516 × 10⁻⁴ m².
