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

Formula

dm³/(cm²·min) = mm/s × 0.006

or dm³/(cm²·min) = mm/s ÷ 166.6666666667

Derivation from SI units:

• 1 mm/s = 0.001 m ÷ 1 s = 1 L/(m²·s)
• 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/s ÷ 0.1666666666667 m/s per dm³/(cm²·min) = 0.006 dm³/(cm²·min)

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

Worked examples

1. A reading of 100 mm/s converts to 0.6 dm³/(cm²·min).
   100 mm/s × 0.006 = 0.6 dm³/(cm²·min)
2. A value of 500 mm/s is 3 dm³/(cm²·min).
   500 mm/s × 0.006 = 3 dm³/(cm²·min)

Where it's used

Millimeters per Second are used for air permeability of fabrics, nonwovens and papers (ISO 9237, EN ISO 9237), while cubic decimeters per square centimeter per minute appear in read-outs on some air permeability testers for open materials. Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
