1. What is GPM to LPS Conversion?

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

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

2. How Does the Conversion Work?

The conversion uses the formula:

\[ Q_{lps} = \frac{Q_{gpm}}{15.850} \]

Where:

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

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

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for system design, pump sizing, and ensuring compatibility between equipment using different measurement systems.

4. Using the Calculator

Tips: Simply enter the flow rate in gallons per minute (GPM) and the calculator will provide the equivalent in liters per second (LPS).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 15.850?
A: It combines 3.78541 (liters per gallon) and 60 (seconds per minute): 3.78541 × 60 ≈ 227.1246, then 227.1246 / 15.850 ≈ 1.

Q2: When would I need to convert GPM to LPS?
A: When working with international specifications, metric system equipment, or when comparing systems using different measurement standards.

Q3: How precise is this conversion?
A: The conversion is precise to several decimal places, suitable for most engineering applications.

Q4: What's a typical GPM value for household plumbing?
A: Standard faucets typically flow at 1-2 GPM (about 0.063-0.126 LPS), while shower heads are often 2.5 GPM (about 0.158 LPS).

Q5: Can I convert LPS back to GPM?
A: Yes, multiply LPS by 15.850 to get GPM.
