| gal/min | Gallon/Minute (US) | 0.26417816 |
| gal/h | Gallon/Hour (US) | 15.850689 |
Formula: gal/h = L/min × 15.85
Multiply any L/min value by 15.85 to get gal/h.
Reverse: L/min = gal/h × 0.06309

1 L/min = 15.85 gal/h.
m³/s × 1000 = L/s × 60 = L/min. Use this chain for quick conversions.
Multiply result by 0.06309 to recover the original L/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.
Liters per minute (L/min) is the standard flow unit in medicine, laboratory equipment, gas regulators, and small pump specifications. It is the most practical scale for flows measured in minutes.
Medical oxygen is prescribed in L/min (1–15 L/min depending on condition). IV drip rates are controlled in mL/min (0.001–1 L/min). Laboratory peristaltic pumps are rated in L/min. Vehicle fuel consumption during testing is measured in L/min.
Interesting fact: A healthy adult kidney filters about 120 mL/min (0.12 L/min) of blood through the glomerulus — this glomerular filtration rate (GFR) is a key indicator of kidney function and decreases with age and disease.
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.
Converting L/min to gal/h 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 L/min = 158.5 gal/h. Reverse: 1 gal/h = 0.06309 L/min. Factor: 1 L/min = 15.85 gal/h.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
