Convert L/(dm²·min) to cm³/(s·cm²)

Formula

cm³/(s·cm²) = L/(dm²·min) × 0.1666666666667

or cm³/(s·cm²) = L/(dm²·min) ÷ 6

Derivation from SI units:

• 1 L/(dm²·min) = 10⁻³ m³ ÷ (10⁻² m² × 60 s) = 1/600 m/s ≈ 1.667 mm/s
• 1 cm³/(s·cm²) = 10⁻⁶ m³ ÷ (10⁻⁴ m² × 1 s) = 0.01 m/s = 1 cm/s
• 1 L/(dm²·min) = 0.001666666666667 m/s ÷ 0.01 m/s per cm³/(s·cm²) = 0.1666666666667 cm³/(s·cm²)

Both units are defined exactly, so the factor is exact. Liter per Square Decimeter per Minute definition: liter per square decimeter per minute; Cubic Centimeter per Second per Square Centimeter definition: cubic centimeter per second per square centimeter.

Worked examples

1. A reading of 20 L/(dm²·min) converts to 3.333333333 cm³/(s·cm²).
   20 L/(dm²·min) × 0.1666666667 = 3.333333333 cm³/(s·cm²)
2. A value of 200 L/(dm²·min) is 33.33333333 cm³/(s·cm²).
   200 L/(dm²·min) × 0.1666666667 = 33.33333333 cm³/(s·cm²)

Where it's used

Liters per Square Decimeter per Minute are used for older European fabric permeability reports (e.g. DIN-based), while cubic centimeters per second per square centimeter appear in ASTM D737 fabric air permeability (SI reporting). Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
