Conversion Formula
nD = cm² × 1.013250000e+17
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 Nanodarcy
The nanodarcy (nD) equals 10⁻⁹ D ≈ 9.869 × 10⁻²² m², the standard permeability unit for ultra-tight unconventional reservoirs. Barnett, Marcellus, and Eagle Ford shale matrix: 1-1 000 nD; crystalline basement rocks and caprocks: below 1 nD. Measured by pulse-decay or GRI crushed-rock methods. 1 nD = 10⁻³ µD = 10⁻⁶ mD.
