Formula: m³/min = CFM × 0.02832
Multiply any CFM value by 0.02832 to get m³/min.
Reverse: CFM = m³/min × 35.31

m³/s × 1000 = L/s × 60 = L/min. Use this chain for quick conversions.
Multiply result by 35.31 to recover the original CFM value.
Designs pumps, pipes, and water distribution systems with flow rates in m³/s, L/s, and GPM.
Specifies air handling units and ductwork in CFM (ft³/min) and m³/h for North American and European projects.
Monitors and controls treatment processes with flow rates in m³/h, L/s, and MGD.
Designs sprinkler systems with required flows in GPM and L/min per NFPA standards.
Measures river and groundwater flows in m³/s (m) and ft³/s (cfs) for flood modeling and water resource planning.
Configures ventilators and oxygen delivery systems with flow rates specified in L/min.
Cubic feet per minute (CFM) is the dominant airflow unit in North American HVAC, ventilation, and pneumatic systems. One CFM = 0.000472 m³/s = 28.32 L/min.
HVAC systems in the US are universally specified in CFM: a typical bedroom requires 50–100 CFM of ventilation; a commercial kitchen exhaust hood needs 300–1,500 CFM; a large data center cooling system may require 100,000+ CFM.
Interesting fact: The term CFM is so entrenched in US building practice that even metric-preferring engineers typically specify airflows in CFM for North American projects. Air compressors are rated in CFM at a specified pressure (e.g., '10 CFM @ 90 psi').
Cubic meters per minute (m³/min) is used for medium-scale industrial flows including ventilation systems, HVAC ducts, pump specifications, and chemical plant processes where per-second rates would be too small.
Industrial fans and blowers are often rated in m³/min. A large HVAC system for a commercial building might circulate 50–500 m³/min. Oxygen and nitrogen generators for industrial use are rated in m³/min output.
Interesting fact: The human respiratory system moves about 0.006–0.01 m³/min at rest, rising to 0.1–0.2 m³/min during heavy exercise. Elite athletes can sustain ventilation rates exceeding 0.2 m³/min.
Converting CFM to m³/min is essential across hydraulic engineering, HVAC, water treatment, fire protection, and medicine. SI units (m³/s, L/s) are standard in science; European engineering uses m³/h; US systems use GPM and CFM; medical applications use L/min.
Quick reference: 10 CFM = 0.2832 m³/min. Reverse: 1 m³/min = 35.31 CFM. Factor: 1 CFM = 0.02832 m³/min.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
