cm²tom²

Convert square centimetres (permeability) (cm²) to square metres (permeability) (m²).

Factor1 cm² = 0.0001 m²

Converter

cm²

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1m²

Rendered to 6 significant figures.

Formula

Formula
m² = cm² × 0.0001

Multiply any value in square centimetres (permeability) by 0.0001 to obtain the value in square metres (permeability).

Worked example

Convert 10000 cm² to m².

  1. 01Start with 10000 cm².
  2. 02Multiply by the conversion factor: 10000 × 0.0001 = 1 m².
Result10000 cm² = 1 m²

FAQ

What is the conversion factor from cm² to m²?
1 cm² equals 0.0001 m². To convert, multiply the value in square centimetres (permeability) by 0.0001.
How do I convert 1 cm² to m²?
1 cm² = 0.0001 m². For any value, multiply by 0.0001.
How do I convert m² back to cm²?
Divide by the same factor — or equivalently, multiply by 10000. So 1 m² = 10000 cm².
When would I need to convert square centimetre (permeability) to square metre (permeability)?
Permeability conversions between cm² and m² 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).
