Flow Rate Conversion Formula:
| From: | To: |
The GPM to m³/hr conversion is used to convert flow rate measurements from gallons per minute (GPM) to cubic meters per hour (m³/hr). This conversion is essential in various engineering, industrial, and scientific applications where fluid flow rates need to be expressed in different unit systems.
The calculator uses the conversion formula:
Where:
Explanation: One gallon per minute equals approximately 0.227 cubic meters per hour. This conversion factor accounts for the volume difference between gallons and cubic meters, and the time conversion from minutes to hours.
Details: Accurate flow rate conversion is crucial in water treatment plants, chemical processing, HVAC systems, and international engineering projects where different measurement systems are used. Proper conversion ensures consistency and accuracy in calculations and specifications.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be non-negative. The calculator will automatically compute the equivalent flow rate in cubic meters per hour (m³/hr).
Q1: What is the exact conversion factor from GPM to m³/hr?
A: The exact conversion factor is 0.22712470704, which is derived from the fact that 1 US gallon = 0.00378541 cubic meters and 1 hour = 60 minutes.
Q2: Are there different types of gallons used in conversion?
A: Yes, this calculator uses US gallons. Imperial gallons (used in UK) have a different conversion factor (1 imperial gallon = 0.00454609 m³).
Q3: When is this conversion commonly used?
A: This conversion is frequently used in water supply systems, irrigation engineering, petroleum industry, and international project specifications.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on standard definitions. However, practical accuracy depends on the precision of your input measurements.
Q5: Can I convert m³/hr back to GPM?
A: Yes, to convert back, use the formula: GPM = m³/hr ÷ 0.22712470704 or multiply by approximately 4.40287.
