1. What is GPM to m³/s Conversion?

The GPM to m³/s conversion calculates flow rate from gallons per minute to cubic meters per second. This conversion is essential in engineering, fluid dynamics, and international unit standardization.

2. How Does the Conversion Work?

The conversion uses the formula:

Where:

• \( GPM \) — Flow rate in gallons per minute
• \( 6.30901964 \times 10^{-5} \) — Conversion factor (0.0000630901964)

Explanation: One gallon per minute equals approximately 0.00006309 cubic meters per second, based on the definition of US gallon (3.78541 liters) and time conversion (60 seconds per minute).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for international engineering projects, hydraulic calculations, pump sizing, and compliance with metric system standards used in scientific research.

4. Using the Converter

Tips: Enter the flow rate in gallons per minute (GPM). The value must be non-negative. The converter will automatically calculate the equivalent flow rate in cubic meters per second.

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The exact conversion factor is 6.30901964 × 10⁻⁵ (0.0000630901964) m³/s per GPM.

Q2: Is this using US gallons or imperial gallons?
A: This conversion uses US gallons (1 US gallon = 3.78541 liters). Imperial gallons would require a different conversion factor.

Q3: Where is this conversion commonly used?
A: Commonly used in water treatment plants, HVAC systems, chemical processing, and international engineering projects requiring metric unit compliance.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on standard unit definitions. Precision depends on the accuracy of the input value.

Q5: Can I convert back from m³/s to GPM?
A: Yes, to convert back, divide the m³/s value by 6.30901964 × 10⁻⁵ or multiply by approximately 15,850.32.
