Convert L/(dm²·min) to dm³/(cm²·min)

Formula

dm³/(cm²·min) = L/(dm²·min) ÷ 100

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 dm³/(cm²·min) = 10⁻³ m³ ÷ (10⁻⁴ m² × 60 s) = 1/6 m/s ≈ 166.7 mm/s
• 1 L/(dm²·min) = 0.001666666666667 m/s ÷ 0.1666666666667 m/s per dm³/(cm²·min) = 0.01 dm³/(cm²·min)

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

Worked examples

1. A reading of 20 L/(dm²·min) converts to 0.2 dm³/(cm²·min).
   20 L/(dm²·min) × 0.01 = 0.2 dm³/(cm²·min)
2. A value of 200 L/(dm²·min) is 2 dm³/(cm²·min).
   200 L/(dm²·min) × 0.01 = 2 dm³/(cm²·min)

Where it's used

Liters per Square Decimeter per Minute are used for older European fabric permeability reports (e.g. DIN-based), 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.
