Convert permeability units including square meters, darcy, millidarcy, microdarcy, square centimeters, square feet, and square inches.
Darcy to square meters:
1 D = 9.86923e-13 m²
Millidarcy to darcy:
1 mD = 0.001 D
Microdarcy to darcy:
1 µD = 0.000001 D
Square meter to darcy:
1 m² = 1.01325e12 D
Permeability conversions are useful for soil testing, groundwater flow, petroleum reservoirs, rock samples, filtration media, geotechnical reports, drainage design, and porous material analysis.
Use this converter when comparing SI permeability units with darcy-based engineering and geology units.
Your result shows the entered permeability converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For engineering, geotechnical, or reservoir work, make sure the permeability unit matches your lab report, soil data, rock property table, model input, or design reference.
Permeability measures how easily a fluid can move through pores or openings in a material.
The SI unit commonly used for permeability is square meters, abbreviated as m².
A darcy is a permeability unit commonly used in petroleum engineering, geology, groundwater, and porous media analysis.
One darcy equals approximately 9.86923 × 10⁻¹³ square meters.
This converter is designed for permeability magnitude conversions, so it uses non-negative values.
