Explanation

Formula: Cubic Feet per Second = Gallons per Minute (US) × 0.002228009. Why: the route uses liters per second as the common basis, then applies the fixed US gallon definition together with the relevant per-minute or per-hour time scaling.

Gallons per Minute (US) (gpm): a US customary volumetric flow unit based on the US liquid gallon and commonly used in pumps, piping, and water systems.

Cubic Feet per Second (cfs): a larger cubic-foot flow unit used for airflow, drainage, and open-channel or hydraulic flow reporting.

This route is useful when comparing imperial and HVAC-style flow units such as gallons per minute and cubic feet so specifications stay on the intended unit system.

This conversion is purely multiplicative because both units reduce through one liters-per-second flow basis with fixed unit-volume definitions and no offset.
