Full API documentation

Explanation

Formula: Cubic Feet per Second = Cubic Feet per Minute × 0.016667. 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 Minute (cfm): an imperial volumetric flow unit widely used for airflow, ventilation, and HVAC system sizing.

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 restating the same cubic-foot flow across per-second and per-minute reporting, especially for airflow, ventilation, and hydraulic references.

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 Minute = 0.016667 Cubic Feet per Second.
Consistency rule: calculator output and table values use the same constants and rounding policy.
