1. What is a LPM to GPM Calculator?

Definition: This calculator converts flow rate from liters per minute (LPM) to gallons per minute (GPM).

Purpose: It helps engineers, technicians, and professionals working with fluid systems to convert between metric and imperial flow rate units.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q_{gpm} = \frac{Q_{lpm}}{3.785} \]

Where:

\( Q_{gpm} \) — Flow rate in gallons per minute (GPM)
\( Q_{lpm} \) — Flow rate in liters per minute (LPM)
3.785 — Conversion factor (liters per gallon)

Explanation: Since 1 US gallon equals approximately 3.785 liters, we divide the LPM value by 3.785 to get GPM.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential when working with international equipment specifications, hydraulic systems, or when comparing performance data across different measurement systems.

4. Using the Calculator

Tips: Simply enter the flow rate in liters per minute (LPM). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the exact conversion factor?
A: 1 US gallon = 3.785411784 liters exactly, but 3.785 is sufficient for most practical applications.

Q2: Does this work for imperial (UK) gallons?
A: No, this uses US gallons. For UK gallons, divide by 4.546 instead.

Q3: When would I need this conversion?
A: When working with pumps, filters, or fluid systems that use different measurement systems in their specifications.

Q4: How precise is this conversion?
A: The calculation is mathematically precise, though actual system performance may vary based on other factors.

Q5: Can I convert GPM to LPM with this?
A: This calculator is one-directional (LPM to GPM). For reverse conversion, multiply GPM by 3.785.
