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

Formula

mL/(s·cm²) = cm/s × 1

Derivation from SI units:

• 1 cm/s = 0.01 m ÷ 1 s = 1 cm³/(s·cm²)
• 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/s ÷ 0.01 m/s per mL/(s·cm²) = 1 mL/(s·cm²)

Both units are defined exactly, so the factor is exact. Centimeter per Second definition: centimeter per second; Milliliter per Second per Square Centimeter definition: milliliter per second per square centimeter.

Worked examples

1. A reading of 2.5 cm/s converts to 2.5 mL/(s·cm²).
   2.5 cm/s × 1 = 2.5 mL/(s·cm²)
2. A value of 14 cm/s is 14 mL/(s·cm²).
   14 cm/s × 1 = 14 mL/(s·cm²)

Where it's used

Centimeters per Second are used for filter media testing (5.33 cm/s = 32 L/min through 100 cm²), while milliliters per second per square centimeter appear in air permeability of papers and membranes. Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
