How to Convert Cubic Foot per Minute to Cubic Meter per Second
- 1 CFM = 0.0004719474432 m³/s
- 1 m³/s = 2118.880003 CFM
- Example: convert 15 CFM to m³/s: 15 CFM = 15 × 0.0004719474432 m³/s = 0.007079211648 m³/s
Formula
m³/s = CFM × 0.0004719474432
or m³/s = CFM ÷ 2118.880003289
Derivation from SI units:
- 1 CFM = (0.3048 m)³ ÷ 60 s = 4.719474432 × 10⁻⁴ m³/s
- 1 m³/s = 1 m³ ÷ 1 s
Both units are defined exactly, so the factor is exact. Cubic Foot per Minute definition: cubic foot per minute; Cubic Meter per Second definition: cubic meter per second.
Worked examples
- A 2000 CFM fan moves 0.9438948864 m³/s.
2000 CFM × 0.0004719474432 = 0.9438948864 m³/s - A 10000 CFM dust collector moves 4.719474432 m³/s.
10000 CFM × 0.0004719474432 = 4.719474432 m³/s
