Flow Rate Conversion:
| From: | To: |
The M3 Per Hr To Gpm conversion calculates the equivalent flow rate in gallons per minute (GPM) from cubic meters per hour (m³/hr). This conversion is essential in fluid dynamics, engineering, and various industrial applications where flow rates need to be converted between metric and imperial units.
The calculator uses the conversion formula:
Where:
Explanation: The 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 engineering calculations, pump sizing, pipeline design, and international projects where different unit systems are used. It ensures consistency and prevents errors in fluid system design and operation.
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: What is the difference between m³/hr and GPM?
A: m³/hr is a metric unit measuring volume flow rate in cubic meters per hour, while GPM is an imperial unit measuring gallons per minute.
Q2: How accurate is the conversion factor?
A: The conversion factor 4.402867539302473 is precise and based on standard unit definitions (1 US gallon = 0.00378541 cubic meters).
Q3: When is this conversion typically used?
A: Commonly used in water treatment plants, hydraulic systems, irrigation design, chemical processing, and international engineering projects.
Q4: Can I convert GPM back to m³/hr?
A: Yes, use the inverse conversion: m³/hr = GPM ÷ 4.402867539302473 or m³/hr = GPM × 0.227124.
Q5: Are there different types of gallons?
A: This calculator uses US gallons. Note that imperial (UK) gallons are different (1 imperial gallon = 1.20095 US gallons).
