How to Convert Millimeter per Second to Foot per Minute
- 1 mm/s = 0.1968503937 ft/min
- 1 ft/min = 5.08 mm/s
- Example: convert 15 mm/s to ft/min: 15 mm/s = 15 × 0.1968503937 ft/min = 2.952755906 ft/min
Formula
ft/min = mm/s × 0.1968503937008
or ft/min = mm/s ÷ 5.08
Derivation from SI units:
- 1 mm/s = 0.001 m ÷ 1 s = 1 L/(m²·s)
- 1 ft/min = 0.3048 m ÷ 60 s = 0.00508 m/s
- 1 mm/s = 0.001 m/s ÷ 0.00508 m/s per ft/min = 0.1968503937008 ft/min
Both units are defined exactly, so the factor is exact. Millimeter per Second definition: millimeter per second; Foot per Minute definition: foot per minute.
Worked examples
- A reading of 100 mm/s converts to 19.68503937 ft/min.
100 mm/s × 0.1968503937 = 19.68503937 ft/min - A value of 500 mm/s is 98.42519685 ft/min.
500 mm/s × 0.1968503937 = 98.42519685 ft/min

Where it's used
Millimeters per Second are used for air permeability of fabrics, nonwovens and papers (ISO 9237, EN ISO 9237), 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.
