About Gallons per Minute (US) and Liters per Minute
Converting gallons per minute (GPM) to liters per minute (LPM) is essential when working with US-specification pumps in metric countries. 1 GPM = 3.7854 LPM exactly (based on the US liquid gallon of 3.785411784 L).
Common Uses for This Conversion
Converting US pump specifications to metric, plumbing design for imported equipment, chemical dosing systems, and agricultural irrigation from US suppliers.
💡Did You Know?
A garden hose at full pressure flows around 9–11 GPM (34–42 LPM). A fire hydrant can deliver over 1,000 GPM (3,785 LPM).
Frequently Asked Questions
To convert LPM to GPM, multiply by 0.2642. For example, 100 LPM × 0.2642 = 26.42 GPM. To convert GPM back to LPM, multiply by 3.7854. This conversion is commonly used in pump sizing, irrigation design, and comparing US and metric flow specifications.
To convert CFM (cubic feet per minute) to m³/h, multiply by 1.6990. For example, 100 CFM × 1.6990 = 169.90 m³/h. To convert m³/h back to CFM, multiply by 0.5886. This is essential for HVAC engineers comparing US and European system specifications.
These are all flow rate units measuring volume per time. 1 L/s = 60 LPM = 3.6 m³/h. Liters per second (L/s) is the SI base unit. Liters per minute (LPM) is common in medical and small industrial equipment. Cubic meters per hour (m³/h) is standard for large industrial pumps, HVAC systems, and water treatment plants.
In India, pump flow rates are most commonly specified in liters per minute (LPM) or liters per hour (LPH) for domestic and agricultural applications. Cubic meters per hour (m³/h) is used for industrial and water treatment plants. GPM (gallons per minute) appears in some imported pump specifications, requiring conversion to LPM for local use.
