Flow Rate Conversion Formula:
| From: | To: |
The GPM to LPM conversion is used to convert flow rates from gallons per minute to liters per minute. This conversion is essential in various fields including engineering, plumbing, irrigation, and fluid dynamics where different measurement systems are used.
The calculator uses the conversion formula:
Where:
Explanation: Since 1 US gallon equals exactly 3.785411784 liters, multiplying gallons per minute by this conversion factor gives the equivalent flow rate in liters per minute.
Details: Accurate flow rate conversion is crucial for international projects, equipment specifications, and ensuring compatibility between systems using different measurement units. It's widely used in water treatment, chemical processing, and hydraulic systems.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The calculator will instantly convert it to liters per minute (LPM) with high precision.
