About Converting Cubic foot per Minutes to Liter per Seconds
Cubic foot per Minutes and Liter per Seconds 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. Cubic foot per Minutes is typically associated with united States, and widely recognized internationally in HVAC and compressed-air equipment specifications, while Liter per Seconds is typically associated with common in municipal water-utility and industrial flow specifications internationally.
Formula
liter per seconds = cubic foot per minutes × 0.4719474432
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per minutes equals 0.0004719474432 base units, and 1 liter per seconds equals 0.001 base units, so dividing one by the other gives the direct cubic foot per minutes-to-liter per seconds factor of 0.4719474432.
Simple example
1 ft3/min × 0.4719474432 = 0.4719474432 L/s
1 cubic foot per minutes = 0.4719474432 liter per seconds.
Real-world example
60 ft3/min × 0.4719474432 = 28.31684659 L/s
60 cubic foot per minutes = 28.31684659 liter per seconds.
Conversion table

Cubic foot per Minutes vs. Liter per Seconds
| Aspect | Cubic foot per Minutes | Liter per Seconds |
|---|---|---|
| Family | US customary flow-rate unit | metric derived flow-rate unit |
| Typical use | The standard unit for rating HVAC airflow, compressed-air equipment output, and fan/blower performance | Municipal water supply and treatment plant flow rates |
| Where it's used | United States, and widely recognized internationally in HVAC and compressed-air equipment specifications | Common in municipal water-utility and industrial flow specifications internationally |
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
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
