Formula: m³/min = gal/h × 6.3090e-5
Multiply any gal/h value by 6.3090e-5 to get m³/min.
Reverse: gal/h = m³/min × 1.585e+04
Common flow rate values — factor: 1 gal/h = 6.3090e-5 m³/min

m³/s × 1000 = L/s × 60 = L/min. Use this chain for quick conversions.
Multiply result by 1.585e+04 to recover the original gal/h 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.
Gallons per hour (gal/h) is used for slower flow rates such as fuel consumption, slow drip irrigation, and residential water softeners. One gal/h = 1.0514 × 10⁻⁶ m³/s ≈ 0.0631 L/min.
Vehicle fuel consumption at highway speeds is typically 2–8 gal/h for gasoline engines. Water softeners regenerate at 0.5–2 gal/h. Fuel oil burners for home heating consume 0.7–3 gal/h depending on output.
Interesting fact: A dripping faucet (one drip per second) wastes about 3,000 gallons per year — roughly 0.34 gal/h. A running toilet can waste 200 gal/h, adding up to nearly 2 million gallons over a year if unrepaired.
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 gal/h 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 gal/h = 0.0006309 m³/min. Reverse: 1 m³/min = 1.585e+04 gal/h. Factor: 1 gal/h = 6.3090e-5 m³/min.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
