Flow Rate Conversion Formula:
| From: | To: |
The GPM to L/min conversion is used to convert flow rate measurements from gallons per minute (GPM) to liters per minute (L/min). This conversion is essential in various engineering, industrial, and scientific applications where fluid flow rates need to be expressed in different unit systems.
The calculator uses the conversion 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 in hydraulic systems, water treatment plants, chemical processing, irrigation systems, and international engineering projects where different measurement systems are used.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be non-negative. The calculator will instantly convert it to liters per minute (L/min) with high precision.
Q1: What is the exact conversion factor from GPM to L/min?
A: The exact conversion factor is 3.785411784, which comes from the definition of 1 US gallon = 3.785411784 liters.
Q2: 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.
Q3: Where is GPM to L/min conversion commonly used?
A: Commonly used in water supply systems, HVAC systems, industrial processes, fire protection systems, and international engineering specifications.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between US gallons and liters.
Q5: Can I convert L/min back to GPM?
A: Yes, to convert back, divide L/min by 3.785411784 or multiply by approximately 0.264172.
