About Metre squared
The square metre (m²) is the SI coherent unit of permeability (dimension [L²]) and the reference for all other permeability units. Most geological materials have k far below 1 m²; clean coarse gravel: ≈10⁻⁸ m²; shale: 10⁻²²-10⁻¹⁵ m². 1 m² = 10¹² µm² ≈ 1.013 × 10¹² D.
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.
