About Converting Liter per Seconds to Cubic foot per Minutes
Liter per Seconds and Cubic foot per Minutes both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Liter per Seconds is typically associated with common in municipal water-utility and industrial flow specifications internationally, while Cubic foot per Minutes is typically associated with united States, and widely recognized internationally in HVAC and compressed-air equipment specifications.
Formula
cubic foot per minutes = liter per seconds × 2.11888000329
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per seconds equals 0.001 base units, and 1 cubic foot per minutes equals 0.0004719474432 base units, so dividing one by the other gives the direct liter per seconds-to-cubic foot per minutes factor of 2.11888000329.
Simple example
1 L/s × 2.118880003 = 2.118880003 ft3/min
1 liter per seconds = 2.118880003 cubic foot per minutes.
Real-world example
60 L/s × 2.118880003 = 127.1328002 ft3/min
60 liter per seconds = 127.1328002 cubic foot per minutes.

Understanding the Liter per Seconds
Liter per Seconds (L/s) measures volumetric flow rate. One liter of volume passing a point every second — used for larger flows than liter-per-minute conveniently describes. It is classified as a metric derived flow-rate unit.
Where it's used: Common in municipal water-utility and industrial flow specifications internationally
L/s vs. L/min. Both measure the same quantity at different time scales; 1 L/s equals 60 L/min. L/s is typically used for larger, continuous industrial or utility flows, while L/min suits smaller household-scale flows.
Uses of the Liter per Seconds today
- Municipal water supply and treatment plant flow rates
- Industrial process flow specifications
- Stream and river discharge measurement at moderate scales
Understanding the Cubic foot per Minutes
Cubic foot per Minutes (ft3/min) measures volumetric flow rate. One cubic foot of volume passing a point every minute. It is classified as a US customary flow-rate unit.
Where it's used: United States, and widely recognized internationally in HVAC and compressed-air equipment specifications
Uses of the Cubic foot per Minutes today
- The standard unit for rating HVAC airflow, compressed-air equipment output, and fan/blower performance
