Flow Rate Conversion Formula:
| From: | To: |
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 engineering, hydraulics, and fluid dynamics applications where international unit standardization is required.
The calculator uses the conversion formula:
Where:
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.
Details: Accurate flow rate conversion is crucial for international engineering projects, hydraulic system design, water treatment plants, and scientific research where consistent unit measurement is essential for calculations and specifications.
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.
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.
Q3: When is this conversion most commonly used?
A: This conversion is frequently used in water supply systems, HVAC engineering, chemical processing, and environmental engineering where flow rates need to be expressed in SI units.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on standard definitions. The calculator provides results with 8 decimal places for precision.
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.
