FAQ

What is the conversion factor from m² to ft²?
1 m² equals 10.76391 ft². To convert, multiply the value in square metres (permeability) by 10.76391.
How do I convert 1 m² to ft²?
1 m² = 10.7639 ft². For any value, multiply by 10.76391.
How do I convert ft² back to m²?
Divide by the same factor — or equivalently, multiply by 0.09290304. So 1 ft² = 0.092903 m².
When would I need to convert square metre (permeability) to square foot (permeability)?
Permeability conversions between m² and ft² appear in petroleum and reservoir engineering, hydrogeology, geotechnical engineering, packed-bed filtration and porous-materials research. The darcy (D) and its sub-multiples (mD, µD, nD) dominate petroleum-engineering documentation; SI area-equivalent units (m², µm², mm², cm², ft²) appear in geophysics and porous-media research. Intrinsic permeability is a property of the porous medium alone — this category does NOT include hydraulic conductivity (m/s, requires fluid density and viscosity), gas permeability (Klinkenberg slip corrections) or membrane-permeability coefficients, all of which are different physical quantities and require explicit assumptions.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
