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 various engineering, hydraulic, 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 accounts for the volume difference between gallons and cubic meters, and the time conversion from minutes to seconds.
Details: Accurate flow rate conversion is crucial in international engineering projects, hydraulic system design, water treatment plants, and scientific research where consistent unit measurement is necessary for proper calculations and system compatibility.
Tips: Enter the flow rate 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?
A: The exact conversion factor is 6.30901964 × 10⁻⁵, which means 1 GPM = 0.0000630901964 m³/s.
Q2: When is this conversion typically used?
A: This conversion is commonly used in water supply systems, HVAC engineering, hydraulic calculations, and international projects where metric units are required.
Q3: How accurate is this conversion?
A: The conversion is mathematically exact based on standard unit definitions. One US gallon is defined as exactly 0.003785411784 cubic meters.
Q4: Are there different types of gallons?
A: Yes, this calculator uses US gallons. Imperial gallons (UK) are approximately 20% larger than US gallons and would require a different conversion factor.
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.
