This converter lists both area-based units (m², cm², in², …) and Darcy units (D, mD). They describe permeability in different formalisms—Darcy comes from porous-media flow (Darcy's law), not from converting plain geometric area. Use area↔area or Darcy↔Darcy for direct comparisons; m²↔D conversions use the hydraulic factors in this tool and are not the same as renaming SI area units.
Converting between area units and Darcy units applies a hydraulic permeability model. The result is not interchangeable with a simple area-unit rename.
