Flow Rate Conversion Formula:
| From: | To: |
Flow rate conversion between liters per minute (lpm) and gallons per minute (gpm) is essential in various engineering and industrial applications where different measurement systems are used.
The calculator uses the conversion formula:
Where:
Explanation: This formula converts flow rate from metric units (liters per minute) to US customary units (gallons per minute).
Details: Accurate flow rate conversion is crucial in various industries including water management, chemical processing, HVAC systems, and hydraulic engineering where different measurement systems are used interchangeably.
Tips: Enter the flow rate in liters per minute (lpm). The value must be a non-negative number. The calculator will automatically compute the equivalent value in gallons per minute (gpm).
Q1: Why is the conversion factor 3.785?
A: This value comes from the definition of a US gallon, which is exactly 3.785411784 liters. For most practical purposes, 3.785 is used as the conversion factor.
Q2: Are there different types of gallons?
A: Yes, there are US gallons (3.785 liters) and imperial gallons (4.546 liters). This calculator uses US gallons, which are standard in most engineering applications.
Q3: When would I need to convert between lpm and gpm?
A: This conversion is commonly needed when working with international equipment specifications, comparing flow rates from different sources, or when documentation uses different measurement systems.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between liters and gallons. The accuracy of your result depends on the precision of your input value.
Q5: Can I convert gpm to lpm using this calculator?
A: This calculator specifically converts from lpm to gpm. To convert from gpm to lpm, you would multiply by 3.785 instead of dividing.
