Flow Rate Conversion:
| From: | To: |
Flow rate conversion between liters per minute (L/min) and gallons per minute (GPM) is essential for various engineering, industrial, and scientific applications where fluid flow measurements need to be standardized across different unit systems.
The conversion uses the following formula:
Where:
Explanation: This conversion factor is derived from the relationship between liters and gallons, where 1 gallon equals approximately 3.78541 liters.
Details: Accurate flow rate conversion is crucial for international projects, equipment specifications, hydraulic calculations, and ensuring compatibility between systems using different measurement standards.
Tips: Enter the flow rate in liters per minute (L/min). The value must be non-negative. The calculator will automatically convert it to gallons per minute (GPM) with high precision.
Q1: Why is the conversion factor so precise?
A: The factor 0.2641720523581484 is exact based on the definition that 1 US gallon = 3.785411784 liters, ensuring maximum accuracy in conversions.
Q2: When would I need to convert between L/min and GPM?
A: Common applications include pump specifications, irrigation systems, chemical processing, water treatment plants, and international engineering projects.
Q3: Is this conversion for US gallons or imperial gallons?
A: This conversion uses US gallons. Imperial gallons are larger (1 imperial gallon = 4.54609 liters), so the conversion factor would be different.
Q4: Can I convert GPM back to L/min?
A: Yes, to convert back, use the formula: L/min = GPM ÷ 0.2641720523581484 or L/min = GPM × 3.785411784.
Q5: What are typical flow rate ranges for common applications?
A: Household faucets: 1-3 GPM (3.8-11.4 L/min), shower heads: 2-2.5 GPM (7.6-9.5 L/min), garden hoses: 5-10 GPM (19-38 L/min).
