Conversion Formula:
| From: | To: |
The US GPM to L/min conversion is used to convert flow rate measurements from US gallons per minute to liters per minute. This conversion is essential in various engineering, industrial, and scientific applications where flow rates need to be expressed in different units.
The conversion uses the following formula:
Where:
Explanation: One US gallon equals exactly 3.785411784 liters, so multiplying the flow rate in US GPM by this factor gives the equivalent flow rate in liters per minute.
Details: Accurate flow rate conversion is crucial in hydraulic systems, fluid dynamics, chemical processing, water treatment, and international engineering projects where different unit systems are used.
Tips: Enter the flow rate in US gallons per minute. The value must be non-negative. The converter will automatically calculate the equivalent flow rate in liters per minute.
Q1: What is the difference between US gallon and imperial gallon?
A: A US gallon is approximately 3.785 liters, while an imperial gallon is about 4.546 liters. This converter specifically uses US gallons.
Q2: When would I need to convert between these units?
A: Common applications include pump specifications, pipe flow calculations, irrigation systems, and international equipment compatibility.
Q3: Is the conversion factor exact?
A: Yes, 1 US gallon is defined as exactly 3.785411784 liters by international agreement.
Q4: Can I convert negative flow rates?
A: No, flow rates should be positive values. Negative values don't have physical meaning in this context.
Q5: How precise should my calculations be?
A: For most engineering applications, 2-4 decimal places are sufficient, but the calculator provides higher precision when needed.
