1. What is a L/min to GPM Calculator?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Flow Rate Conversion

Details: Accurate conversion between units is essential when working with international specifications, equipment from different regions, or when documentation uses mixed units.

4. Using the Calculator

Tips: Simply enter the flow rate in liters per minute (must be > 0) and the calculator will display the equivalent in gallons per minute.

5. Frequently Asked Questions (FAQ)

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

Q2: Does this work for UK gallons?
A: No, UK gallons are different (1 UK gallon = 4.54609 liters). Use 4.546 as the conversion factor for UK gallons.

Q3: What's a typical flow rate in plumbing?
A: Standard household faucets typically deliver 1.5-2.2 GPM (5.7-8.3 L/min), while showerheads are often limited to 2.5 GPM (9.5 L/min).

Q4: How accurate is this conversion?
A: The conversion is mathematically exact. Any inaccuracy would come from rounding the result.

Q5: Can I convert GPM back to L/min?
A: Yes, multiply GPM by 3.785 to get L/min. We may add this reverse calculation in a future update.
