Convert Milliliters per Second per Square Centimeter to m/s

Formula

m/s = mL/(s·cm²) ÷ 100

Derivation from SI units:

• 1 mL/(s·cm²) = 10⁻⁶ m³ ÷ (10⁻⁴ m² × 1 s) = 0.01 m/s = 1 cm/s
• 1 m/s = 1 m ÷ 1 s (equivalently 1 m³/s of flow per 1 m² of area)

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

Worked examples

1. A reading of 5 mL/(s·cm²) converts to 0.05 m/s.
   5 mL/(s·cm²) × 0.01 = 0.05 m/s
2. A value of 25 mL/(s·cm²) is 0.25 m/s.
   25 mL/(s·cm²) × 0.01 = 0.25 m/s

Where it's used

Milliliters per Second per Square Centimeter are used for air permeability of papers and membranes, while meters per second appear in filter face velocity (ISO 16890 full-size filters ≈ 2.7 m/s). Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
