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

Formula

dm/s = cm³/(s·cm²) ÷ 10

Derivation from SI units:

• 1 cm³/(s·cm²) = 10⁻⁶ m³ ÷ (10⁻⁴ m² × 1 s) = 0.01 m/s = 1 cm/s
• 1 dm/s = 0.1 m ÷ 1 s
• 1 cm³/(s·cm²) = 0.01 m/s ÷ 0.1 m/s per dm/s = 0.1 dm/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; Decimeter per Second definition: decimeter per second.

Worked examples

1. A reading of 5 cm³/(s·cm²) converts to 0.5 dm/s.
   5 cm³/(s·cm²) × 0.1 = 0.5 dm/s
2. A value of 25 cm³/(s·cm²) is 2.5 dm/s.
   25 cm³/(s·cm²) × 0.1 = 2.5 dm/s

Where it's used

Cubic Centimeters per Second per Square Centimeter are used for ASTM D737 fabric air permeability (SI reporting), while decimeters per second appear in occasional instrument read-outs. Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
