About Converting Liter per Seconds to Cubic foot per Days
Liter per Seconds and Cubic foot per Days 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 most often used for municipal water supply and treatment plant flow rates.
Formula
cubic foot per days = liter per seconds × 3051.18720474
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 days equals 3.277413e-7 base units, so dividing one by the other gives the direct liter per seconds-to-cubic foot per days factor of 3051.18720474.
Simple example
1 L/s × 3051.187205 = 3,051.187205 ft3/d
1 liter per seconds = 3,051.187205 cubic foot per days.
Real-world example
60 L/s × 3051.187205 = 183,071.2323 ft3/d
60 liter per seconds = 183,071.2323 cubic foot per days.

Reverse conversion: Cubic foot per Days to Liter per Seconds
1 ft3/d × 0.00032774128 = 0.0003277413 L/s
1 cubic foot per days = 0.0003277413 liter per seconds.
liter per seconds = cubic foot per days × 0.00032774128

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
