nm² = mD × 986.9232667
About Millidarcy
The millidarcy (mD) equals 10⁻³ D ≈ 9.869 × 10⁻¹⁶ m², the everyday unit in petroleum reservoir engineering worldwide. Conventional sandstone reservoirs: 1-1 000 mD; carbonate reservoirs: 0.1-100 mD; economic gas recovery typically requires k ≥ 0.1 mD. Permeameter and well-test reports give results in mD. 1 mD = 10⁻³ D = 10³ µD.
About Nanometre squared
The nanometre squared (nm²) equals 10⁻¹⁸ m², used in membrane science and nanotechnology for nanoporous media. ZSM-5 zeolite pore cross-section ≈ 0.25 nm²; ceramic ultrafiltration membranes: 0.01-1 nm². Numerically, 1 nm² ≈ 1.013 µD. 1 nm² = 10⁻⁶ µm² = 10⁻¹⁸ m².
