The US GPM to m³/hr conversion is used to convert flow rate measurements from US gallons per minute to cubic meters per hour. This conversion is essential in various engineering, industrial, and scientific applications where different unit systems are used.
The calculator uses the conversion formula:
Where:
Explanation: One US gallon per minute equals approximately 0.227 cubic meters per hour. The conversion factor is derived from the relationship between gallons and cubic meters, and minutes to hours.
Details: Accurate flow rate conversion is crucial in water treatment plants, chemical processing, irrigation 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 US gallons per minute (US 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 difference between US gallon and imperial gallon?
A: A US gallon is approximately 3.785 liters, while an imperial gallon is about 4.546 liters. This calculator specifically uses US gallons.
Q2: How accurate is the conversion factor?
A: The conversion factor 0.22712470704 is highly precise, derived from exact unit definitions (1 US gallon = 0.00378541 m³, 1 hour = 60 minutes).
Q3: When is this conversion typically used?
A: Commonly used in water supply systems, HVAC calculations, industrial fluid handling, and international engineering projects where metric units are required.
Q4: Can I convert m³/hr back to US GPM?
A: Yes, to convert back, use the formula: US GPM = m³/hr ÷ 0.22712470704 or multiply by approximately 4.40287.
Q5: Are there any limitations to this conversion?
A: This conversion is purely mathematical and assumes standard conditions. It doesn't account for fluid properties, temperature, or pressure effects on flow rate measurements.
