1. What is US GPM to m³/s Conversion?

The US GPM to m³/s conversion calculator converts flow rate measurements from US gallons per minute to cubic meters per second. This conversion is essential for engineering, hydraulics, and fluid dynamics applications where international unit standardization is required.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( US GPM \) — Flow rate in US gallons per minute
• \( 6.30901964 \times 10^{-5} \) — Conversion factor
• \( m³/s \) — Result in cubic meters per second

Explanation: One US gallon per minute equals approximately 0.00006309 cubic meters per second.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international engineering projects, pump sizing, pipeline design, and hydraulic calculations where different measurement systems are used.

4. Using the Calculator

Tips: Enter the flow rate in US gallons per minute. The value must be non-negative. The calculator will instantly convert it to cubic meters per second.
