1. What is a LPH to GPH Calculator?

Definition: This calculator converts flow rate from liters per hour (LPH) to gallons per hour (GPH).

Purpose: It helps in fluid dynamics calculations, fuel consumption measurements, and various engineering applications where unit conversion is needed.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q_{gph} = \frac{Q_{lph}}{3.785} \]

Where:

\( Q_{gph} \) — Flow rate in gallons per hour (GPH)
\( Q_{lph} \) — Flow rate in liters per hour (LPH)
3.785 — Conversion factor (liters per gallon)

Explanation: The conversion is based on the fact that 1 US gallon equals exactly 3.785 liters.

3. Importance of Flow Rate Conversion

Details: Accurate unit conversion ensures proper system design, performance evaluation, and compliance with different measurement standards.

4. Using the Calculator

Tips: Simply enter the flow rate in liters per hour (LPH) and the calculator will automatically compute the equivalent in gallons per hour (GPH).
