Convert mL/(s·cm²) to Liters per Square Meter per Second

Formula

L/(m²·s) = mL/(s·cm²) × 10

Derivation from SI units:

• 1 mL/(s·cm²) = 10⁻⁶ m³ ÷ (10⁻⁴ m² × 1 s) = 0.01 m/s = 1 cm/s
• 1 L/(m²·s) = 10⁻³ m³ ÷ (1 m² × 1 s) = 10⁻³ m/s = 1 mm/s
• 1 mL/(s·cm²) = 0.01 m/s ÷ 0.001 m/s per L/(m²·s) = 10 L/(m²·s)

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

Worked examples

1. A reading of 5 mL/(s·cm²) converts to 50 L/(m²·s).
   5 mL/(s·cm²) × 10 = 50 L/(m²·s)
2. A value of 25 mL/(s·cm²) is 250 L/(m²·s).
   25 mL/(s·cm²) × 10 = 250 L/(m²·s)

Where it's used

Milliliters per Second per Square Centimeter are used for air permeability of papers and membranes, 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.
