1. What is L/min to GPM Conversion?

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

Purpose: It helps engineers, technicians, and professionals working with fluid systems to easily 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 (L/min)
3.785 — Conversion factor (liters per US gallon)

Explanation: Since 1 US gallon equals approximately 3.785 liters, dividing L/min by this value converts it to GPM.

3. Importance of Flow Rate Conversion

Details: Accurate conversion between units is essential when working with international specifications, equipment with different unit systems, or when comparing performance data.

4. Using the Calculator

Tips: Simply enter the flow rate in liters per minute (L/min) and the calculator will instantly provide the equivalent in gallons per minute (GPM).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3.785?
A: This is the exact conversion between liters and US gallons (1 US gallon = 3.785411784 liters).

Q2: Does this calculator use US or UK gallons?
A: This calculator uses US gallons. For UK gallons, the conversion factor would be 4.546.

Q3: What are common applications for this conversion?
