Convert Decimeters per Second to L/(m²·s)

Formula

L/(m²·s) = dm/s × 100

Derivation from SI units:

• 1 dm/s = 0.1 m ÷ 1 s
• 1 L/(m²·s) = 10⁻³ m³ ÷ (1 m² × 1 s) = 10⁻³ m/s = 1 mm/s
• 1 dm/s = 0.1 m/s ÷ 0.001 m/s per L/(m²·s) = 100 L/(m²·s)

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

Worked examples

1. A reading of 2 dm/s converts to 200 L/(m²·s).
   2 dm/s × 100 = 200 L/(m²·s)
2. A value of 20 dm/s is 2000 L/(m²·s).
   20 dm/s × 100 = 2000 L/(m²·s)

Where it's used

Decimeters per Second are used for occasional instrument read-outs, while liters per square meter per second appear in fabric and nonwoven air permeability (EN ISO 9237 at 100 Pa or 200 Pa). Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
