Formula: GPM = m³/min × 264.2
Multiply any m³/min value by 264.2 to get GPM.
Reverse: m³/min = GPM × 0.003785

1 m³/min = 264.2 GPM.
m³/s × 1000 = L/s × 60 = L/min. Use this chain for quick conversions.
Multiply result by 0.003785 to recover the original m³/min 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 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.
Gallons per minute (GPM) is the standard flow unit for pumps, plumbing, fire suppression, and irrigation systems in the United States. One US GPM = 6.309 × 10⁻⁵ m³/s = 3.785 L/min.
US pump specifications universally use GPM: a residential well pump delivers 5–20 GPM; a fire suppression sprinkler system requires 7–26 GPM per head; a municipal fire hydrant delivers 500–1,500 GPM. Fuel transfer pumps at gas stations operate at 10–15 GPM.
Interesting fact: The US uses about 345 billion gallons of freshwater per day — approximately 240 million GPM. Of this, about 41% goes to thermoelectric power plant cooling, 37% to irrigation, and 13% to public water supplies.
Converting m³/min to GPM 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 m³/min = 2642 GPM. Reverse: 1 GPM = 0.003785 m³/min. Factor: 1 m³/min = 264.2 GPM.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
