1 µm²= 1.01325 D= 1e-12 m² (k)= 1013.25 mD
10 µm²= 10.1325 D= 1e-11 m² (k)= 10132.5 mD
100 µm²= 101.325 D= 1e-10 m² (k)= 101325 mD
1000 µm²= 1013.25 D= 1e-9 m² (k)= 1013250 mD

Where the square micrometer fits

The next smaller permeability (porous media) unit is the darcy (D). 1 µm² = 1.01325 D, and 1 D ≈ 0.9869232667 µm².

The next larger permeability (porous media) unit is the square meter (permeability) (m² (k)). 1 µm² = 1e-12 m² (k), and 1 m² (k) = 1000000000000 µm².
