1. What is LS to GPM Conversion?

LS to GPM conversion is used to convert flow rates from liters per second (L/s) to gallons per minute (GPM). This conversion is essential in various engineering and fluid dynamics applications where different measurement systems are used.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

\[ Q_{gpm} = Q_{ls} \times 15.85 \]

Where:

\( Q_{gpm} \) — Flow rate in gallons per minute
\( Q_{ls} \) — Flow rate in liters per second
15.85 — Conversion factor from L/s to GPM

Explanation: The conversion factor 15.85 is derived from the relationship between liters and gallons (1 gallon = 3.78541 liters) and seconds to minutes (1 minute = 60 seconds).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial in hydraulic engineering, plumbing, irrigation systems, and industrial processes where measurements may be specified in different units across international standards.

4. Using the Calculator

Tips: Enter the flow rate in liters per second (L/s). The value must be positive. The calculator will automatically convert it to gallons per minute (GPM).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 15.85?
A: The factor comes from: 1 L/s = (1/3.78541) gal/s × 60 s/min = 15.85 GPM, accounting for both volume and time unit conversions.

Q2: What are typical flow rates in L/s and GPM?
A: Residential water supply: 0.1-0.5 L/s (1.6-7.9 GPM), Fire hydrants: 5-15 L/s (79-238 GPM), Industrial pumps: 10-100+ L/s (159-1585+ GPM).

Q3: When is this conversion most commonly used?
A: Commonly used in water supply systems, hydraulic engineering projects, pump specifications, and when working with equipment from different countries.

Q4: Are there limitations to this conversion?
A: The conversion is mathematically exact. However, ensure you're using US gallons (3.78541 L) rather than imperial gallons (4.54609 L) which would give a different factor.

Q5: Can I convert GPM back to L/s?
A: Yes, use the inverse formula: Q_ls = Q_gpm ÷ 15.85 or Q_ls = Q_gpm × 0.0631.
