Convert Milliliters per Second per Square Centimeter to cm/s

Formula

cm/s = mL/(s·cm²) × 1

Derivation from SI units:

• 1 mL/(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 mL/(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. Milliliter per Second per Square Centimeter definition: milliliter per second per square centimeter; Centimeter per Second definition: centimeter per second.

Worked examples

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

Where it's used

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