1. What is a LS to GPM Calculator?

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

Purpose: It helps engineers, plumbers, and technicians 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 (GPM)
• \( Q_{ls} \) — Flow rate in liters per second (L/s)
• 15.850 — Conversion factor (exact value is 15.85032314)

Explanation: The conversion factor accounts for both volume (1 liter = 0.264172 gallons) and time (1 second = 1/60 minutes) conversions.

3. Importance of Flow Rate Conversion

Details: Accurate conversion between units is essential for system design, pump selection, and compliance with different measurement standards.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 15.850?
A: It combines the liter-to-gallon (0.264172) and seconds-to-minutes (60) conversions: 0.264172 × 60 = 15.85032.

Q2: How precise is this conversion?
A: The factor used (15.850) provides precision to 3 decimal places. For most applications, this is sufficient.

Q3: When would I need to convert L/s to GPM?
A: When working with international specifications, comparing pump ratings, or using equipment with different unit systems.

Q4: What's a typical flow rate in L/s?
A: Residential water supply might be 0.2-0.5 L/s, while fire sprinkler systems could require 10-20 L/s.

Q5: Can I convert GPM back to L/s?
A: Yes, divide GPM by 15.850 or use our GPM to L/s calculator.
