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

Formula

cm³/(s·cm²) = L/(m²·s) ÷ 10

Derivation from SI units:

• 1 L/(m²·s) = 10⁻³ m³ ÷ (1 m² × 1 s) = 10⁻³ m/s = 1 mm/s
• 1 cm³/(s·cm²) = 10⁻⁶ m³ ÷ (10⁻⁴ m² × 1 s) = 0.01 m/s = 1 cm/s
• 1 L/(m²·s) = 0.001 m/s ÷ 0.01 m/s per cm³/(s·cm²) = 0.1 cm³/(s·cm²)

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

Worked examples

1. 100 L/(m²·s) is exactly 10 cm³/(s·cm²).
   100 L/(m²·s) × 0.1 = 10 cm³/(s·cm²)
2. 300 L/(m²·s) is 30 cm³/(s·cm²).
   300 L/(m²·s) × 0.1 = 30 cm³/(s·cm²)

Where it's used

Converting ISO 9237 L/(m²·s) results to ASTM D737 SI units is a factor of 10 exactly: 10 L/(m²·s) = 1 cm³/(s·cm²).
