Explanation

Both units describe volumetric flow rate, so the time basis already matches and only the volume unit changes. The converter does not adjust a gas flow for pressure, temperature, or standard conditions.

Multiply cubic feet per minute by approximately 28.316846592.

Conversion Basis

Multiply cubic feet per minute by approximately 28.316846592.
For 25 CFM, the result is about 707.9211648 liters per minute.
The snapshot, calculator, common values, and reverse route use the same conversion basis.

Reference & Scope

The volume factor follows from the international cubic-foot definition; process-condition corrections are outside this unit conversion.

Questions & answers

Frequently Asked Questions

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

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

What fixed factor powers this Cubic Feet per Minute to Liters per Minute 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 minute to liters per minute?

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 Minute to Liters per Minute?

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