Convert Liters per Square Meter per Second to dm³/(cm²·min)

Formula

dm³/(cm²·min) = L/(m²·s) × 0.006

or dm³/(cm²·min) = L/(m²·s) ÷ 166.6666666667

Derivation from SI units:

• 1 L/(m²·s) = 10⁻³ m³ ÷ (1 m² × 1 s) = 10⁻³ m/s = 1 mm/s
• 1 dm³/(cm²·min) = 10⁻³ m³ ÷ (10⁻⁴ m² × 60 s) = 1/6 m/s ≈ 166.7 mm/s
• 1 L/(m²·s) = 0.001 m/s ÷ 0.1666666666667 m/s per dm³/(cm²·min) = 0.006 dm³/(cm²·min)

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

Worked examples

1. A reading of 75 L/(m²·s) converts to 0.45 dm³/(cm²·min).
   75 L/(m²·s) × 0.006 = 0.45 dm³/(cm²·min)
2. A value of 500 L/(m²·s) is 3 dm³/(cm²·min).
   500 L/(m²·s) × 0.006 = 3 dm³/(cm²·min)

Where it's used

Liters per Square Meter per Second are used for fabric and nonwoven air permeability (EN ISO 9237 at 100 Pa or 200 Pa), while cubic decimeters per square centimeter per minute appear in read-outs on some air permeability testers for open materials. Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
