1. What is a GPM to LPS Converter?

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

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:

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

Where:

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

Explanation: The conversion factor comes from the relationship between gallons and liters (1 gallon = 3.78541 liters) and minutes to seconds (1 minute = 60 seconds).

3. Importance of Flow Rate Conversion

Details: Accurate conversion between measurement systems is crucial for international projects, equipment specifications, and system design.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why convert GPM to LPS?
A: Many countries use metric units (LPS) while some equipment uses imperial units (GPM), requiring conversion for compatibility.

Q2: What's the exact conversion factor?
A: 1 GPM = 0.06309 LPS (or 1 LPS = 15.850 GPM) based on standard gallon and liter definitions.

Q3: When would I need this conversion?
A: When working with international standards, metric system equipment, or comparing flow rates from different sources.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact, though real-world measurements may have instrument errors.

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