What Is This Tool?
This converter translates flow measurements from cubic foot per hour—a common imperial volumetric flow unit—to gallon (UK) per second, a unit representing the volume of one UK gallon passing each second. It supports various engineering and process applications where both US and imperial UK volumes are involved.
How to Use This Tool?
-
Enter the flow rate in cubic foot per hour (ft³/h) into the input field
-
Choose gallon (UK) per second as the target unit
-
Click the convert button to see the equivalent flow rate
-
Review the result and apply it to your engineering or process calculations
Key Features
-
Converts volumetric flow rates from cubic foot/hour to gallon (UK)/second seamlessly
-
Supports units widely used in HVAC, gas metering, waterworks, and industrial flow monitoring
-
Browser-based and easy to use without installation
-
Includes clear examples to guide accurate conversions
-
Helps ensure compatibility between US customary and UK imperial units for flow
Examples
-
10 cubic foot/hour converts to 0.017302321 gallon (UK)/second
-
50 cubic foot/hour converts to 0.086511605 gallon (UK)/second
Common Use Cases
-
Determining ventilation or exhaust system flow rates in HVAC design
-
Measuring natural gas or compressed air flows in pipelines
-
Specifying pump and meter capacities in UK-based water systems
-
Reporting flow rates for firefighting and hydrant testing with imperial units
-
Translating documentation and specifications between US and UK measurement systems
Tips & Best Practices
-
Ensure consistent units are used throughout your calculations to avoid errors
-
Be mindful of the difference in volumetric definitions between US cubic feet and UK gallons
-
Account for time unit differences when comparing or converting flow rates
-
Use multiple conversion steps cautiously to minimize rounding errors
-
Verify conversions under varying temperature and pressure conditions if exact precision is critical
Limitations
-
Differences in time bases (hour vs second) and volume units may cause confusion if not handled carefully
-
Rounding during repeated conversions can affect accuracy
-
Real fluid volume can change with temperature and pressure, which this converter does not adjust for
Frequently Asked Questions
-
What does cubic foot per hour measure?
-
It measures the volume of one cubic foot of fluid moving past a point or through a cross-section in one hour.
-
Why convert cubic foot/hour to gallon (UK)/second?
-
To align flow measurements with systems and documentation that use UK imperial units and measure flow per second instead of per hour.
-
Can I use this converter for gas pipelines?
-
Yes, it is suitable for measuring gas flows such as natural gas or compressed air in pipelines and related metering equipment.
Key Terminology
