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.

About Millimetre squared

The millimetre squared (mm²) equals 10⁻⁶ m² ≈ 1.013 × 10⁹ D, representing extremely high permeabilities beyond the range of most geological materials. It appears in geotechnical research for open rock fractures, coarse gravel channel beds, and large-cell open-foam engineered materials. 1 mm² = 10⁶ µm² = 10⁻⁶ m².
