About Centimetre squared

The centimetre squared (cm²) equals 10⁻⁴ m² ≈ 1.013 × 10¹¹ D, present in unit-conversion tables as a logical extension of the SI area series. It is effectively beyond the range of any natural porous medium and arises only in theoretical packed-bed studies or large-aperture industrial filter specifications. 1 cm² = 10⁴ mm² = 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.
