Flow Rate Conversion Formula:
| From: | To: |
Flow rate conversion between gallons per minute (GPM) and cubic meters per hour (m³/hr) is essential in various engineering, industrial, and environmental applications where fluid flow measurements need to be standardized across different unit systems.
The conversion uses the following formula:
Where:
Explanation: This conversion factor accounts for the relationship between US gallons and cubic meters (1 gallon = 0.00378541 m³) and the time conversion from minutes to hours (60 minutes = 1 hour).
Details: Accurate flow rate conversion is crucial for international engineering projects, fluid system design, pump specifications, and environmental monitoring where different measurement systems are used.
Tips: Enter the flow rate in gallons per minute (GPM). The calculator will automatically convert it to cubic meters per hour (m³/hr). The default value of 600 GPM is pre-filled for quick conversion.
Q1: Why convert between GPM and m³/hr?
A: Different industries and countries use different measurement systems. Conversion ensures accurate communication and specification compatibility in international projects.
Q2: What is the conversion factor based on?
A: The factor 0.22712470704 comes from: 1 gallon = 0.00378541 m³ and 60 minutes = 1 hour, so 1 GPM = 0.00378541 × 60 = 0.2271246 m³/hr.
Q3: Are there different types of gallons?
A: Yes, this calculator uses US gallons. Imperial gallons (UK) have a different conversion factor (1 imperial gallon = 0.00454609 m³).
Q4: When is this conversion most commonly used?
A: Commonly used in water treatment, HVAC systems, petroleum industry, chemical processing, and irrigation system design.
Q5: How accurate is this conversion?
A: The conversion is mathematically exact based on standard unit definitions. Practical accuracy depends on the precision of your input measurements.
