1. What is L/s to GPM Conversion?

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

Purpose: It helps engineers, plumbers, and technicians work with flow rate measurements in different unit systems.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q_{gpm} = Q_{ls} \times 15.850 \]

Where:

\( Q_{gpm} \) — Flow rate in gallons per minute
\( Q_{ls} \) — Flow rate in liters per second
15.850 — Conversion factor (1 L/s = 15.850 GPM)

Explanation: The conversion factor accounts for both volume (liters to gallons) and time (seconds to minutes) conversions.

3. Importance of Flow Rate Conversion

Details: Many engineering specifications and equipment use different measurement systems, making conversions essential for accurate system design and operation.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 15.850?
A: It combines 1 liter = 0.264172 gallons and 1 second = 1/60 minutes (0.264172 × 60 = 15.850).

Q2: When would I need this conversion?
A: When working with international specifications, pump curves, or fluid systems that use different measurement standards.

Q3: How accurate is this conversion?
A: The conversion factor provides precision to 6 significant figures, sufficient for most engineering applications.

Q4: Can I convert GPM back to L/s?
A: Yes, divide GPM by 15.850 to get L/s (or use our GPM to L/s calculator).

Q5: Does this work for any liquid?
A: Yes, as long as you're measuring volumetric flow rate (not mass flow rate).
