Flow Rate Conversion Formula:
From: | To: |
Flow rate conversion between cubic meters per hour (m³/h) and gallons per minute (GPM) is essential for engineers, technicians, and professionals working with fluid systems across different measurement standards.
The converter uses the precise conversion formula:
Where:
Explanation: This conversion factor is derived from the relationship between cubic meters and gallons, and hours to minutes (1 m³ = 264.172 gallons, 1 hour = 60 minutes).
Details: Accurate flow rate conversion is crucial for international engineering projects, pump sizing, pipeline design, and ensuring compatibility between systems using different measurement units.
Tips: Enter the flow rate in cubic meters per hour (m³/h). The value must be positive. The converter will instantly calculate the equivalent flow rate in gallons per minute (GPM).
Q1: Why is the conversion factor 4.402867539302473?
A: This precise factor comes from: 1 m³/h = (264.172 gallons) / (60 minutes) = 4.402867539302473 GPM.
Q2: When would I need to convert between m³/h and GPM?
A: Common in water treatment plants, HVAC systems, industrial processes, and when working with equipment specifications from different countries.
Q3: Is this conversion accurate for all fluids?
A: Yes, the conversion is volumetric and applies to all fluids. However, mass flow rates would require density considerations.
Q4: What's the difference between US gallon and imperial gallon?
A: This converter uses US gallons (1 US gallon = 3.78541 liters). Imperial gallons are larger (1 imperial gallon = 4.54609 liters).
Q5: Can I convert GPM back to m³/h?
A: Yes, use the inverse: m³/h = GPM ÷ 4.402867539302473 or m³/h = GPM × 0.227124.
