Liter per Square Decimeter per Minute (L/(dm²·min))
The litre per square decimetre per minute, L/(dm²·min), is an air permeability unit used by some European textile laboratories. It equals 1/600 m/s, about 1.667 mm/s.
Symbol: L/(dm²·min) (ASCII: L/dm2/min)
Quantity: face velocity and air permeability (volumetric flow per unit area)
SI relation: 1 L/(dm²·min) = 0.001666666666667 m/s (exact)
Derivation: 1 L/(dm²·min) = 10⁻³ m³ ÷ (10⁻² m² × 60 s) = 1/600 m/s ≈ 1.667 mm/s
Exact: yes, by definition
Typical uses
- Older European fabric permeability reports (e.g. DIN-based)
- Converting legacy specifications to mm/s or L/(m²·s)
