1. What is US GPM to m³/hr Conversion?

This conversion tool calculates flow rate from US gallons per minute (US GPM) to cubic meters per hour (m³/hr). This is commonly used in engineering, fluid dynamics, and industrial applications where flow rates need to be converted between imperial and metric units.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( US GPM \) — Flow rate in US gallons per minute
• \( 0.22712470704 \) — Conversion factor
• \( m³/hr \) — Result in cubic meters per hour

Explanation: One US gallon per minute equals approximately 0.227 cubic meters per hour based on standard conversion factors.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for international engineering projects, equipment specifications, fluid system design, and compliance with different measurement standards used worldwide.

4. Using the Calculator

Tips: Enter the flow rate in US gallons per minute. The value must be non-negative. The calculator will automatically convert to cubic meters per hour with high precision.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between US gallon and imperial gallon?
A: US gallon is approximately 3.785 liters, while imperial gallon is about 4.546 liters. This calculator uses US gallons.

Q2: How accurate is this conversion?
A: The conversion factor 0.22712470704 is precise and based on standard unit definitions (1 US gallon = 3.785411784 liters).
