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 different unit systems are used.
The conversion uses the following formula:
Where:
Explanation: The conversion factor is derived from the relationship between gallons and cubic meters, and minutes to hours. One US gallon equals approximately 0.00378541 cubic meters, and there are 60 minutes in an hour.
Details: Accurate flow rate conversion is crucial for international engineering projects, fluid dynamics calculations, pump sizing, pipeline design, and process engineering where different measurement systems are used.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be non-negative. The calculator will automatically convert it to cubic meters per hour (m³/hr) with high precision.
Q1: What is the exact conversion factor?
A: The exact conversion factor is 0.22712470704, which is derived from 1 gallon = 0.003785411784 cubic meters and 60 minutes per hour.
Q2: Is this for US gallons or imperial gallons?
A: This conversion uses US gallons (1 US gallon = 3.785411784 liters). Imperial gallons are larger (1 imperial gallon = 4.54609 liters).
Q3: When is this conversion typically used?
A: Commonly used in water treatment plants, chemical processing, HVAC systems, irrigation design, and any application involving fluid flow measurements.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact when using the precise conversion factor. Rounding may occur in practical applications.
Q5: Can I convert back from m³/hr to GPM?
A: Yes, to convert back, divide m³/hr by 0.22712470704 or multiply by approximately 4.40287.
