1. What is USGPM to LPS Conversion?

Definition: This calculator converts flow rate from US 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 Calculator Work?

The calculator uses the formula:

Where:

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

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 unit conversion ensures proper system design, specification compatibility, and international project coordination.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's the exact conversion factor?
A: 1 US GPM = 0.0630901964 L/s, or more practically 1/15.850 L/s.

Q2: How does this differ from Imperial GPM?
A: US gallon is 3.785 liters while Imperial gallon is 4.546 liters - ensure you're using the correct gallon type.

Q3: When would I need this conversion?
A: When working with international specifications, metric system requirements, or comparing system performance data.

Q4: What's a typical GPM value for household plumbing?
A: Standard faucets flow at 1.5-2.5 GPM (0.095-0.158 L/s), while showers typically use 2.0-2.5 GPM.

Q5: How precise is this conversion?
A: The calculator provides 3 decimal places, sufficient for most engineering applications.
