About Microdarcy
The microdarcy (µD) equals 10⁻⁶ D ≈ 9.869 × 10⁻¹⁹ m², used for tight gas sands, coalbed methane matrix, and low-permeability carbonates. North Sea tight sandstones: 0.01-1 µD; coalbed methane matrix: 1-100 µD; mudrock caprocks: 0.001-1 µD. 1 µD = 10⁻³ mD = 10³ nD.
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.
