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

Formula

cm/s = cm³/(s·cm²) × 1

Derivation from SI units:

• 1 cm³/(s·cm²) = 10⁻⁶ m³ ÷ (10⁻⁴ m² × 1 s) = 0.01 m/s = 1 cm/s
• 1 cm/s = 0.01 m ÷ 1 s = 1 cm³/(s·cm²)
• 1 cm³/(s·cm²) = 0.01 m/s ÷ 0.01 m/s per cm/s = 1 cm/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; Centimeter per Second definition: centimeter per second.

Worked examples

1. A reading of 5 cm³/(s·cm²) converts to 5 cm/s.
   5 cm³/(s·cm²) × 1 = 5 cm/s
2. A value of 25 cm³/(s·cm²) is 25 cm/s.
   25 cm³/(s·cm²) × 1 = 25 cm/s

Where it's used

Cubic Centimeters per Second per Square Centimeter are used for ASTM D737 fabric air permeability (SI reporting), while centimeters per second appear in filter media testing (5.33 cm/s = 32 L/min through 100 cm²). Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
