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.
About Micrometre squared
The micrometre squared (µm²) equals 10⁻¹² m², the SI-consistent permeability unit used in European reservoir standards and ISO documents. 1 µm² ≈ 1.0133 D - numerically close to but distinct from the darcy. Clean gravel: 1-10 µm²; clean sandstone: 10⁻³-0.1 µm². 1 µm² = 10⁶ nm² = 10⁻⁶ mm².
