What Is This Tool?
This converter helps transform flow rates measured in cubic foot per second into cubic yard per second, both used widely in US customary and engineering contexts to quantify fluid discharge or throughput.
How to Use This Tool?
-
Enter the volume flow value in cubic foot per second (ft³/s)
-
Select cubic foot/second as the source unit
-
Choose cubic yard/second (yd³/s) as the target unit
-
Start the conversion to obtain the equivalent flow rate
Key Features
-
Converts volumetric flow between cubic foot/second and cubic yard/second
-
Browser-based and easy to use with straightforward input and output
-
Supports common engineering and hydrology measurement units
-
Displays results suitable for pump design, irrigation, and flood forecasting
Examples
-
Convert 10 ft³/s to yd³/s: 10 × 0.037037037 = 0.37037037 yd³/s
-
Convert 50 ft³/s to yd³/s: 50 × 0.037037037 = 1.85185185 yd³/s
Common Use Cases
-
Reporting river and stream discharge in hydrology
-
Designing pumps, pipes, and irrigation channels
-
Sizing open-channel conveyance and stormwater drainage systems
-
Specifying flow rates for hydraulic turbines and large ventilation systems
Tips & Best Practices
-
Use this conversion to express large volumetric flows in more practical units
-
Ensure input values are accurate for hydrology and engineering calculations
-
Validate conversions especially in civil water projects and flood forecasting
Limitations
-
Conversion depends on different unit volumes (cubic foot vs cubic yard) so rounding may reduce precision
-
Best suited for larger flow rates; very small flows can result in extremely small values
-
Focused on US customary units and specific engineering contexts only
Frequently Asked Questions
-
What does cubic foot/second measure?
-
It measures the volume of fluid passing a point each second, commonly used to quantify discharge or throughput in US customary systems.
-
Why convert cubic foot/second to cubic yard/second?
-
Converting helps express large flow rates more suitably in engineering and hydraulics, using a larger unit more practical for substantial volumes.
-
Is this conversion useful for small flow measurements?
-
It is mainly beneficial for larger flow rates; for very small flows, the cubic yard per second values may become impractically tiny.
Key Terminology
-
Cubic foot/second [ft³/s]
-
An imperial unit of volumetric flow representing one cubic foot of fluid passing a point per second, frequently used in US customary systems.
-
Cubic yard/second [yd³/s]
-
A volumetric flow rate unit denoting one cubic yard of fluid passing a point every second, commonly applied in US engineering and hydraulics.
-
Volumetric Flow Rate
-
The volume of fluid which passes through a given surface per unit time.
