What Is This Tool?
This online converter allows you to transform volumetric flow rates from cubic foot per second (ft³/s), a common US/imperial unit, into gallon (UK) per second, which is used in British imperial measurements. It is useful for engineers, hydrologists, and professionals working with fluid flow data between different unit systems.
How to Use This Tool?
-
Enter the value of flow rate in cubic foot per second you want to convert.
-
Select 'cubic foot/second [ft³/s]' as the source unit.
-
Choose 'gallon (UK)/second' as the target unit.
-
Click convert to see the equivalent value in UK gallons per second.
Key Features
-
Converts cubic foot per second to gallon (UK) per second accurately.
-
Browser-based tool requiring no installation.
-
Supports flow rate conversions relevant to hydrology, irrigation, industrial, and firefighting applications.
-
Quickly translate between US customary and imperial UK units.
-
Displays results based on standard volumetric flow conversion rate.
Examples
-
Convert 2 ft³/s: 2 × 6.2288354593 = 12.4576709186 gallon (UK)/second.
-
Convert 0.5 ft³/s: 0.5 × 6.2288354593 = 3.11441772965 gallon (UK)/second.
Common Use Cases
-
River and stream discharge measurements for hydrology and flood forecasting.
-
Designing pumps, pipes, and channels in irrigation and wastewater systems.
-
Sizing flow rates for hydraulic turbines and ventilation systems.
-
Specifying pump or meter capacity on systems using imperial UK units.
-
Reporting flows in water supply, hydrant testing, or firefighting setups.
-
Describing flow rates in industrial processes or vessel systems retaining imperial documentation.
Tips & Best Practices
-
Ensure units are correctly selected before performing the conversion.
-
Use this conversion when working with steady flow conditions for best results.
-
Verify unit consistency when documenting or reporting flows across different measurement systems.
-
Double-check conversion results when used in regulatory or technical documentation.
Limitations
-
The conversion assumes steady flow and does not consider fluid compressibility or temperature effects.
-
Differences in measurement systems mean caution is needed in regions strictly adhering to one unit standard.
-
Conversion does not address changes in physical fluid properties affecting volume.
Frequently Asked Questions
-
What does 1 cubic foot per second represent?
-
It represents a volumetric flow rate of one cubic foot of fluid passing a point every second, commonly used in engineering and hydrology.
-
Why convert cubic foot per second to gallon (UK) per second?
-
To translate volumes from US customary units to British imperial units, especially for waterworks, industrial processes, and hydrology where UK gallons are standard.
-
Are there any conditions affecting the conversion accuracy?
-
Yes, the conversion assumes steady flow and does not factor in compressibility or temperature changes that might alter fluid volume.
Key Terminology
-
Cubic foot per second (ft³/s)
-
A unit measuring volumetric flow as one cubic foot of fluid passing a point every second, used mainly in hydrology and engineering.
-
Gallon (UK) per second
-
A volumetric flow unit denoting one imperial gallon of fluid passing per second; one UK gallon equals 4.54609 litres.
-
Volumetric flow rate
-
The measurement of fluid volume passing through a point in a system per unit of time.
