Flow Rate Conversion:
| From: | To: |
The M3 Hr to GPM conversion is used to convert flow rates from cubic meters per hour (m³/hr) to gallons per minute (GPM). This conversion is essential in various engineering, industrial, and fluid dynamics applications where different measurement systems are used.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor accounts for the volume difference between cubic meters and gallons, and the time conversion from hours to minutes.
Details: Accurate flow rate conversion is crucial for international engineering projects, fluid system design, pump selection, and ensuring compatibility between systems using different measurement standards.
Tips: Enter the flow rate in cubic meters per hour (m³/hr). The value must be non-negative. The calculator will instantly provide the equivalent flow rate in gallons per minute (GPM).
Q1: Why is the conversion factor 4.402867539302474?
A: This factor comes from the relationship where 1 cubic meter = 264.172 gallons and 1 hour = 60 minutes, so 1 m³/hr = 264.172/60 = 4.402867 GPM.
Q2: When is this conversion typically used?
A: Commonly used in water treatment plants, hydraulic systems, irrigation design, and any application involving fluid flow where metric and imperial units need to be reconciled.
Q3: How accurate is this conversion?
A: The conversion factor is mathematically precise. Accuracy depends on the precision of your input value and the specific definition of gallons used (US liquid gallons are standard for this conversion).
Q4: Can I convert GPM back to m³/hr?
A: Yes, to convert back, divide GPM by 4.402867539302474 or multiply by approximately 0.2271.
Q5: Are there different types of gallons that affect the conversion?
A: This calculator uses US liquid gallons. Imperial gallons (UK) would require a different conversion factor of approximately 3.666.
