Convert Meters per Second to L/(dm²·min)

Formula

L/(dm²·min) = m/s × 600

Derivation from SI units:

• 1 m/s = 1 m ÷ 1 s (equivalently 1 m³/s of flow per 1 m² of area)
• 1 L/(dm²·min) = 10⁻³ m³ ÷ (10⁻² m² × 60 s) = 1/600 m/s ≈ 1.667 mm/s

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

Worked examples

1. A reading of 0.4 m/s converts to 240 L/(dm²·min).
   0.4 m/s × 600 = 240 L/(dm²·min)
2. A value of 2 m/s is 1200 L/(dm²·min).
   2 m/s × 600 = 1200 L/(dm²·min)

Where it's used

Meters per Second are used for filter face velocity (ISO 16890 full-size filters ≈ 2.7 m/s), while liters per square decimeter per minute appear in older European fabric permeability reports (e.g. DIN-based). Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
