About Converting Liter per Seconds to Cup per Days
Liter per Seconds and Cup 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
cup per days = liter per seconds × 365191.44518
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 cup per days equals 2.73829e-9 base units, so dividing one by the other gives the direct liter per seconds-to-cup per days factor of 365191.44518.
Simple example
1 L/s × 365191.4452 = 365,191.4452 cup/d
1 liter per seconds = 365,191.4452 cup per days.
Real-world example
60 L/s × 365191.4452 = 21,911,486.71 cup/d
60 liter per seconds = 21,911,486.71 cup per days.

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

What is a 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.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
Is the liter per seconds to cup per days conversion exact?
Yes. Both liter per seconds and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 365191.4452 used above is exact to as many digits as you choose to display.
What is the difference between 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.
