Full API documentation

Explanation

Formula: Liters per Second = Cubic Feet per Second × 28.317. Why: the route converts both units through liters per second using the exact cubic-foot definition and the matching time-base scaling.

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

Liters per Second (L/s): an SI-style volumetric flow unit used to express how many liters move each second.

This route is useful when translating between SI flow units and gallon- or cubic-foot-based reporting for pumps, piping, ventilation, and plant documentation.

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

Method & Reference

Method basis: exact conversion formula shown in Snapshot.
Applied factor: 1 Cubic Foot per Second = 28.317 Liters per Second.
Consistency rule: calculator output and table values use the same constants and rounding policy.
