What Is This Tool?

This converter allows you to transform flow measurements from cubic foot per second (ft^3/s), a unit often used in hydrology and engineering for large volumetric rates, into US gallons per day (gal (US)/d), commonly applied for household water consumption and small-scale flow measurements.

How to Use This Tool?

  • Enter the volumetric flow value in cubic foot per second (ft^3/s).
  • Select gallon (US) per day [gal (US)/d] as the target unit.
  • Click the convert button to obtain the equivalent flow rate.
  • Review the converted value to support your hydrology or engineering analysis.

Key Features

  • Converts flow rates between cubic foot per second and gallon (US) per day.
  • Supports units common in hydrology, engineering, water treatment, and plumbing.
  • Uses a precise fixed conversion rate of 1 ft^3/s equals 646,316.88314858 gal (US)/d.
  • Browser-based and easy to use with fast results.
  • Suitable for interpreting large and small volumetric flow data across different time scales.

Examples

  • Convert 2 ft^3/s: 2 × 646,316.88314858 = 1,292,633.77 gal (US)/d
  • Convert 0.5 ft^3/s: 0.5 × 646,316.88314858 = 323,158.44 gal (US)/d

Common Use Cases

  • Reporting river and stream discharge for hydrology and flood forecasting.
  • Designing pumps, pipes, and irrigation systems using standard flow units.
  • Sizing flow rates for hydraulic turbines and large HVAC systems.
  • Monitoring household or per-capita water consumption in the US.
  • Evaluating chemical dosing rates and leak flows in water treatment and plumbing.

Tips & Best Practices

  • Verify stable flow conditions before applying the conversion.
  • Be mindful of the unit time difference—seconds versus days—when interpreting results.
  • Use the tool for approximate daily flow understanding and communication.
  • Check flow consistency to ensure meaningful conversion outcomes.

Limitations

  • Conversion produces very large numbers due to differing unit magnitudes, which can be impractical for very small flow rates.
  • Time base differences require accurate time measurement to maintain conversion validity.
  • Does not consider temporal variations or intermittent flow changes.

Frequently Asked Questions

What does one cubic foot per second represent?
It represents an imperial/US customary flow rate unit where one cubic foot of fluid passes a point every second, commonly used in engineering and hydrology.

Why convert from cubic foot/second to gallon (US)/day?
This conversion helps translate large hydrology or engineering flow measurements into daily volume units useful for household or small-scale water usage analysis.

Are the units compatible in terms of time?
They differ in time base—cubic foot/second uses seconds while gallon (US)/day uses days—so an accurate time basis is essential during conversion.

Key Terminology

Cubic foot per second (ft^3/s)
A flow rate unit equal to one cubic foot of fluid passing a point per second, used primarily in hydrology and engineering.
Gallon (US) per day (gal (US)/d)
A volumetric flow rate unit representing one US liquid gallon passing a point in one day, common in water consumption and small-scale flow contexts.
