Convert dm³/(cm²·min) to Millimeters per Second

Formula

mm/s = dm³/(cm²·min) × 166.6666666667

Derivation from SI units:

• 1 dm³/(cm²·min) = 10⁻³ m³ ÷ (10⁻⁴ m² × 60 s) = 1/6 m/s ≈ 166.7 mm/s
• 1 mm/s = 0.001 m ÷ 1 s = 1 L/(m²·s)
• 1 dm³/(cm²·min) = 0.1666666666667 m/s ÷ 0.001 m/s per mm/s = 166.6666666667 mm/s

Both units are defined exactly, so the factor is exact. Cubic Decimeter per Square Centimeter per Minute definition: cubic decimeter per square centimeter per minute; Millimeter per Second definition: millimeter per second.

Worked examples

1. A reading of 0.1 dm³/(cm²·min) converts to 16.66666667 mm/s.
   0.1 dm³/(cm²·min) × 166.6666667 = 16.66666667 mm/s
2. A value of 1 dm³/(cm²·min) is 166.6666667 mm/s.
   1 dm³/(cm²·min) × 166.6666667 = 166.6666667 mm/s

Where it's used

Cubic Decimeters per Square Centimeter per Minute are used for read-outs on some air permeability testers for open materials, while millimeters per second appear in air permeability of fabrics, nonwovens and papers (ISO 9237, EN ISO 9237). Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
