How to Convert Cubic Meter per Second to Cubic Foot per Minute
- 1 m³/s = 2118.880003 CFM
- 1 CFM = 0.0004719474432 m³/s
- Example: convert 15 m³/s to CFM: 15 m³/s = 15 × 2118.880003 CFM = 31783.20005 CFM
Formula
CFM = m³/s × 2118.880003289
Derivation from SI units:
- 1 m³/s = 1 m³ ÷ 1 s
- 1 CFM = (0.3048 m)³ ÷ 60 s = 4.719474432 × 10⁻⁴ m³/s
Both units are defined exactly, so the factor is exact. Cubic Meter per Second definition: cubic meter per second; Cubic Foot per Minute definition: cubic foot per minute.
Worked examples
- The ISO 16890 rated test airflow, 0.944 m³/s, is 2000.222723 CFM.
0.944 m³/s × 2118.880003 = 2000.222723 CFM - 1 m³/s is 2118.880003 CFM.
1 m³/s × 2118.880003 = 2118.880003 CFM
