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.

Frequently Asked Questions

What is 1 cubic foot per second in liters per second?

1 Cubic Foot per Second equals 28.317 Liters per Second on this page.

What fixed factor powers this Cubic Feet per Second to Liters per Second page?

The factor is derived by normalizing both units through liters per second, then applying the exact cubic-foot definition together with the route's matching time-base scaling.

When would I convert cubic feet per second to liters per 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.

How do I reverse Cubic Feet per Second to Liters per Second?

Use the mirror Liters per Second to Cubic Feet per Second route; it applies the inverse relationship with the same flow-rate assumptions.
