How to Convert CFM per Square Foot to Meter per Second
- 1 ft³/(ft²·min) = 0.00508 m/s
- 1 m/s = 196.8503937 ft³/(ft²·min)
- Example: convert 15 ft³/(ft²·min) to m/s: 15 ft³/(ft²·min) = 15 × 0.00508 m/s = 0.0762 m/s
Formula
m/s = ft³/(ft²·min) × 0.00508
or m/s = ft³/(ft²·min) ÷ 196.8503937008
Derivation from SI units:
- 1 ft³/(ft²·min) = 0.3048³ m³ ÷ (0.3048² m² × 60 s) = 0.00508 m/s = 1 ft/min
- 1 m/s = 1 m ÷ 1 s (equivalently 1 m³/s of flow per 1 m² of area)
Both units are defined exactly, so the factor is exact. CFM per Square Foot definition: cubic foot per square foot per minute; Meter per Second definition: meter per second.
Worked examples
- A reading of 25 ft³/(ft²·min) converts to 0.127 m/s.
25 ft³/(ft²·min) × 0.00508 = 0.127 m/s - A value of 100 ft³/(ft²·min) is 0.508 m/s.
100 ft³/(ft²·min) × 0.00508 = 0.508 m/s

Where it's used
CFM per Square Foot are used for ASTM D737 fabric air permeability (inch-pound reporting), while meters per second appear in filter face velocity (ISO 16890 full-size filters ≈ 2.7 m/s). Both measure face velocity and air permeability (volumetric flow per unit area), so the conversion is a fixed factor.

Frequently asked questions
How many meters per second are in 1 cubic foot per square foot per minute?
1 ft³/(ft²·min) = 0.00508 m/s.
How do I convert cubic feet per square foot per minute to meters per second?
Multiply the value in ft³/(ft²·min) by 0.00508, or divide it by 196.8503937. For example, 15 ft³/(ft²·min) × 0.00508 = 0.0762 m/s.
Is the ft³/(ft²·min) to m/s conversion exact?
Yes. Both units are defined exactly, and 1 ft³/(ft²·min) is exactly 0.00508 m/s.
