Convert Millimeters per Second to cm³/(s·cm²)

Formula

cm³/(s·cm²) = mm/s ÷ 10

Derivation from SI units:

• 1 mm/s = 0.001 m ÷ 1 s = 1 L/(m²·s)
• 1 cm³/(s·cm²) = 10⁻⁶ m³ ÷ (10⁻⁴ m² × 1 s) = 0.01 m/s = 1 cm/s
• 1 mm/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. Millimeter per Second definition: millimeter per second; Cubic Centimeter per Second per Square Centimeter definition: cubic centimeter per second per square centimeter.

Worked examples

1. A reading of 100 mm/s converts to 10 cm³/(s·cm²).
   100 mm/s × 0.1 = 10 cm³/(s·cm²)
2. A value of 500 mm/s is 50 cm³/(s·cm²).
   500 mm/s × 0.1 = 50 cm³/(s·cm²)

Where it's used

Millimeters per Second are used for air permeability of fabrics, nonwovens and papers (ISO 9237, EN ISO 9237), while cubic centimeters per second per square centimeter appear in ASTM D737 fabric air permeability (SI reporting). Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
