1. What is US GPM to LPM Conversion?

The US GPM to LPM converter transforms flow rate measurements from US gallons per minute to liters per minute. This conversion is essential for international standardization and scientific calculations where metric units are required.

2. How Does the Converter Work?

The converter uses the standard conversion formula:

Where:

• \( LPM \) — Liters per minute
• \( US \text{ GPM} \) — US gallons per minute
• \( 3.785411784 \) — Conversion factor (liters per US gallon)

Explanation: One US gallon equals exactly 3.785411784 liters, making this conversion straightforward and precise.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for engineering applications, fluid dynamics calculations, pump specifications, irrigation systems, and international project collaboration where different measurement systems are used.

4. Using the Converter

Tips: Enter the flow rate in US gallons per minute. The value must be non-negative. The converter will instantly calculate the equivalent flow rate in liters per minute with high precision.
