Conversion Formula
cm² = mm² × 0.01
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.
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.
