Convert cm³/(s·cm²) to Liters per Square Meter per Second

Formula

L/(m²·s) = cm³/(s·cm²) × 10

Derivation from SI units:

• 1 cm³/(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 cm³/(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. Cubic Centimeter per Second per Square Centimeter definition: cubic centimeter per second per square centimeter; Liter per Square Meter per Second definition: liter per square meter per second.

Worked examples

1. 1 cm³/(s·cm²) is exactly 10 L/(m²·s).
   1 cm³/(s·cm²) × 10 = 10 L/(m²·s)
2. A fabric at 15 cm³/(s·cm²) is 150 L/(m²·s).
   15 cm³/(s·cm²) × 10 = 150 L/(m²·s)

Where it's used

ASTM D737 SI results are converted to L/(m²·s) to compare with European datasheets. Multiply by 10.
