1. What is GPM to m³/s Conversion?

The GPM to m³/s conversion is used to convert flow rate measurements from gallons per minute (GPM) to cubic meters per second (m³/s). This conversion is essential in various engineering, hydraulic, and fluid dynamics applications where metric units are required.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( GPM \) — Flow rate in gallons per minute
• \( 6.30901964 \times 10^{-5} \) — Conversion factor from GPM to m³/s

Explanation: One gallon per minute equals approximately 0.00006309 cubic meters per second. The conversion factor is derived from the relationship between US gallons and cubic meters.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial in international engineering projects, hydraulic system design, water treatment plants, and scientific research where consistent metric units are required for calculations and specifications.

4. Using the Calculator

Tips: Enter the flow rate value in gallons per minute (GPM). The value must be non-negative. The calculator will automatically convert it to cubic meters per second (m³/s) with high precision.

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor from GPM to m³/s?
A: The exact conversion factor is 6.30901964 × 10⁻⁵ m³/s per GPM, based on the US gallon definition (1 gallon = 0.00378541 cubic meters).

Q2: Are there different gallon definitions that affect conversion?
A: Yes, this calculator uses the US gallon (3.78541 liters). The Imperial gallon (4.54609 liters) would require a different conversion factor of approximately 7.57682 × 10⁻⁵ m³/s per GPM.

Q3: What are typical flow rates in GPM and their m³/s equivalents?
A: Common conversions: 1 GPM = 0.00006309 m³/s, 10 GPM = 0.0006309 m³/s, 100 GPM = 0.006309 m³/s, 1000 GPM = 0.06309 m³/s.

Q4: When is this conversion most commonly used?
A: This conversion is frequently used in water supply systems, HVAC engineering, industrial processes, environmental studies, and international project specifications.

Q5: How precise is this conversion?
A: The conversion factor used provides precision to 8 decimal places, which is sufficient for most engineering and scientific applications.
