Why are the converted values so small?

Because gallons per day measure low daily volumes, converting to cubic yards per second results in very small values due to the difference in scale and time units.

When should I use this conversion?

When you need to relate daily low-flow measurements, like household water use, to large-scale hydraulic flows expressed per second.

Is this conversion exact for all flow values?

Due to rounding and scale differences, very low flow rates may have limited precision after conversion.

Common Use Cases

Reporting household or per-capita water consumption in the US
Describing low-rate well or groundwater yield measurements
Specifying chemical dosing and leak rates in water treatment
Expressing river discharge and flood flows in US customary units
Sizing open-channel conveyance and stormwater drainage systems
Determining large-scale pump or irrigation canal flows

Tips & Best Practices

Use scientific notation when interpreting very small results
Understand the difference in scale between the units for proper application
Apply this conversion mainly when linking small and large flow rate data
Double-check flow values for rounding when dealing with low rates

Limitations

Converted values tend to be very small and may need scientific notation
Accuracy can be affected by rounding in low flow rate conversions
The conversion mainly bridges flow data across different magnitude scales
Not intended for direct operational equivalence due to scale differences

Key Terminology

Gallon (US)/day [gal (US)/d]: A unit measuring volume flow equal to one US liquid gallon passing a point each day, used for low-rate water flows.
Cubic yard/second [yd^3/s]: A volumetric flow unit indicating one cubic yard of fluid passing a point every second, common in engineering and hydraulics.
Volumetric Flow Rate: The volume of fluid passing a point in a unit of time.
