Convert dm³/(cm²·min) to Feet per Minute

Formula

ft/min = dm³/(cm²·min) × 32.80839895013

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 ft/min = 0.3048 m ÷ 60 s = 0.00508 m/s
• 1 dm³/(cm²·min) = 0.1666666666667 m/s ÷ 0.00508 m/s per ft/min = 32.80839895013 ft/min

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; Foot per Minute definition: foot per minute.

Worked examples

1. A reading of 0.1 dm³/(cm²·min) converts to 3.280839895 ft/min.
   0.1 dm³/(cm²·min) × 32.80839895 = 3.280839895 ft/min
2. A value of 1 dm³/(cm²·min) is 32.80839895 ft/min.
   1 dm³/(cm²·min) × 32.80839895 = 32.80839895 ft/min

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 feet per minute appear in fume hood face velocity (commonly 80–120 fpm). Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.
