Conversion Formula
D = cm² × 101325000
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 Darcy
The darcy (D) ≈ 9.869 × 10⁻¹³ m², the oilfield-standard permeability unit defined by Darcy's law: 1 D passes 1 cm³/s of 1 cP fluid through 1 cm² cross-section under a 1 atm/cm gradient. Highly permeable consolidated sandstone: 1-5 D; unconsolidated sand: 5-20 D. 1 D = 1 000 mD ≈ 0.9869 µm².
