Cubic Meters per Second to Cubic Feet per Second

Snapshot

1 Cubic Meter per Second equals 35.315 Cubic Feet per Second. Conversion Encyclopedia uses the same fixed conversion basis across the calculator, common values, and reverse page for this page.

Reference basis: This conversion uses a fixed factor based on time-normalized rate definitions.
Example: For 0.1 Cubic Meters per Second, the result equals 3.531 Cubic Feet per Second.
Use the reverse page if you need the opposite direction with the same basis.

Full API documentation

Explanation

Formula: Cubic Feet per Second = Cubic Meters per Second × 35.315. Why: the route converts both units through liters per second using the exact cubic-foot definition and the matching time-base scaling.

Cubic Meters per Second (m³/s): a large SI volumetric flow unit used for high-capacity process, hydraulic, and infrastructure flow reporting.

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 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 Meter per Second = 35.315 Cubic Feet per Second.
Consistency rule: calculator output and table values use the same constants and rounding policy.
