The flow rate converter is a free online tool that helps you convert between engineering units quickly and accurately. It supports 5 units including Liter per minute (L/min), Gallon per minute (GPM), Cubic meter per second (m³/s), Cubic foot per second (ft³/s), Milliliter per second (ml/s). The core conversion formula is: 1 L/min = 0.264172 GPM. For example, 1 Liter per minute equals approximately 0.264172 Gallon per minute. Conversely, 1 Gallon per minute equals approximately 3.785413 Liter per minute. Common conversions: 5 L/min = 1.32086 GPM, 10 L/min = 2.64172 GPM, 25 L/min = 6.6043 GPM, 50 L/min = 13.2086 GPM, 100 L/min = 26.4172 GPM. This converter is useful for students, engineers, scientists, and professionals who need accurate engineering unit conversions. Whether you are working on homework, technical specifications, research data, or everyday measurements, this tool provides instant, reliable results. All conversions are calculated relative to a single base unit for consistency and precision across all supported units. A typical shower uses 2-2.5 GPM. Industrial pumps can move thousands of gallons per minute.
