Convert Liters per Square Decimeter per Minute to mL/(s·cm²)

Formula

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

or mL/(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 mL/(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 mL/(s·cm²) = 0.1666666666667 mL/(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; Milliliter per Second per Square Centimeter definition: milliliter per second per square centimeter.

Worked examples

1. A reading of 20 L/(dm²·min) converts to 3.333333333 mL/(s·cm²).
   20 L/(dm²·min) × 0.1666666667 = 3.333333333 mL/(s·cm²)
2. A value of 200 L/(dm²·min) is 33.33333333 mL/(s·cm²).
   200 L/(dm²·min) × 0.1666666667 = 33.33333333 mL/(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 milliliters per second per square centimeter appear in air permeability of papers and membranes. Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
