1. What is US GPM to ft³/hr Conversion?

The US GPM to ft³/hr conversion is used to convert flow rates from US gallons per minute to cubic feet per hour. This conversion is commonly used in fluid dynamics, plumbing, irrigation systems, and industrial applications where different units of flow measurement are required.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( US\ GPM \) — Flow rate in US gallons per minute
• \( 8.020833333333333 \) — Conversion factor (exact value)

Explanation: The conversion factor is derived from the relationship between US gallons and cubic feet, and the conversion from minutes to hours.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for engineering calculations, system design, pump sizing, and ensuring compatibility between different measurement systems used in various industries.

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 it to cubic feet per hour with high precision.
