Convert Meters per Second to Feet per Minute

Formula

ft/min = m/s × 196.8503937008

Derivation from SI units:

• 1 m/s = 1 m ÷ 1 s (equivalently 1 m³/s of flow per 1 m² of area)
• 1 ft/min = 0.3048 m ÷ 60 s = 0.00508 m/s

Both units are defined exactly, so the factor is exact. Meter per Second definition: meter per second; Foot per Minute definition: foot per minute.

Worked examples

1. A fume hood face velocity of 0.5 m/s is 98.42519685 ft/min.
   0.5 m/s × 196.8503937 = 98.42519685 ft/min
2. A filter face velocity of 2.5 m/s is 492.1259843 ft/min.
   2.5 m/s × 196.8503937 = 492.1259843 ft/min

Where it's used

Laboratory ventilation and filter specifications in m/s are converted to fpm for US standards and test reports. One m/s is about 196.85 fpm.
