Flow Rate Conversion Formula:
| From: | To: |
GPM to LPM conversion is the process of converting flow rate measurements from gallons per minute (GPM) to liters per minute (LPM). This conversion is essential in various engineering, industrial, and scientific applications where fluid flow rates need to be expressed in different unit systems.
The conversion uses the following formula:
Where:
Explanation: Since 1 US gallon equals exactly 3.785411784 liters, multiplying GPM by this conversion factor gives the equivalent flow rate in liters per minute.
Details: Accurate flow rate conversion is crucial for international engineering projects, fluid system design, pump specifications, and ensuring compatibility between equipment using different measurement systems. It's particularly important in water treatment, chemical processing, and HVAC systems.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The converter will automatically calculate the equivalent flow rate in liters per minute (LPM) with high precision.
Q1: What is the exact conversion factor from GPM to LPM?
A: The exact conversion factor is 3.785411784, which comes from the definition of 1 US gallon = 3.785411784 liters.
Q2: Are there different types of gallons?
A: Yes, this converter uses US gallons. Imperial gallons (UK) are larger (1 imperial gallon = 4.54609 liters), so the conversion factor would be different.
Q3: When is GPM to LPM conversion commonly used?
A: Commonly used in international engineering projects, pump specifications, fluid dynamics calculations, and when working with equipment from different countries that use different measurement systems.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between US gallons and liters. The precision depends on the input value accuracy.
Q5: Can I convert LPM back to GPM?
A: Yes, to convert LPM to GPM, divide the LPM value by 3.785411784 (GPM = LPM ÷ 3.785411784).
