1. What is a USGPM to LPM Calculator?

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

Purpose: It helps engineers, technicians, and professionals working with fluid systems to convert between these common flow rate units.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q_{lpm} = Q_{gpm} \times 3.785 \]

Where:

\( Q_{lpm} \) — Flow rate in liters per minute (LPM)
\( Q_{gpm} \) — Flow rate in US gallons per minute (GPM)
3.785 — Conversion factor (1 US gallon = 3.785 liters)

Explanation: The conversion is a simple multiplication since 1 US gallon equals exactly 3.785 liters.

3. Importance of Flow Rate Conversion

Details: Accurate conversion between units is essential for system design, equipment specification, and international collaboration in fluid systems.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Is this conversion different for Imperial gallons?
A: Yes, Imperial gallons are larger (1 Imperial gallon = 4.546 liters). This calculator is specifically for US gallons.

Q2: What's the precision of the conversion factor?
A: The factor 3.785 is exact for US gallons to liters conversion.

Q3: Can I convert LPM back to GPM with this calculator?
A: No, this is a one-way conversion. For reverse conversion, you would divide by 3.785 instead.

Q4: Where is this conversion commonly used?
A: In water systems, hydraulic systems, fuel flow measurements, and any application where flow rates are measured in different unit systems.

Q5: Does this account for temperature or pressure effects?
A: No, this is a simple unit conversion. For precise work, consider temperature and pressure effects on fluid density.
