Flow Rate Conversion Formula:
| From: | To: |
GPM to LPM conversion is the process of converting flow rate measurements 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, hydraulic calculations, and ensuring compatibility between systems using different measurement units. It's widely used in water treatment, chemical processing, and industrial applications.
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 (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: Is this conversion for US gallons or imperial gallons?
A: This calculator uses US gallons. Imperial gallons are larger (1 imperial gallon = 4.54609 liters), so the conversion factor would be different.
Q3: What are typical flow rates in GPM and LPM?
A: Typical household faucet: 1-2 GPM (3.8-7.6 LPM), shower: 2-3 GPM (7.6-11.4 LPM), garden hose: 5-10 GPM (19-38 LPM).
Q4: Why is flow rate conversion important in engineering?
A: Engineers need to convert between units for international standards compliance, equipment sizing, pump selection, and system design calculations.
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).
