Milliliter per Second per Square Centimeter (mL/(s·cm²))
The millilitre per second per square centimetre, mL/(s·cm²), is a permeability unit identical to cm³/(s·cm²) and therefore to 1 cm/s.
Symbol: mL/(s·cm²) (ASCII: mL/s/cm2)
Quantity: face velocity and air permeability (volumetric flow per unit area)
SI relation: 1 mL/(s·cm²) = 0.01 m/s (exact)
Derivation: 1 mL/(s·cm²) = 10⁻⁶ m³ ÷ (10⁻⁴ m² × 1 s) = 0.01 m/s = 1 cm/s
Exact: yes, by definition
Same quantity as centimeter per second (cm/s) , cubic centimeter per second per square centimeter (cm³/(s·cm²)) : the factor between them is exactly 1.
Typical uses
- Air permeability of papers and membranes
- Laboratory permeability instruments that read flow in mL/s
