About Converting Cup per Seconds to Liter per Seconds
Cup per Seconds 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. Both are volumetric flow rate units.
Formula
liter per seconds = cup per seconds × 0.2365882365
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per seconds equals 0.0002365882365 base units, and 1 liter per seconds equals 0.001 base units, so dividing one by the other gives the direct cup per seconds-to-liter per seconds factor of 0.2365882365.
Simple example
1 cup/s × 0.2365882365 = 0.2365882365 L/s
1 cup per seconds = 0.2365882365 liter per seconds.
Real-world example
60 cup/s × 0.2365882365 = 14.19529419 L/s
60 cup per seconds = 14.19529419 liter per seconds.

Understanding the Cup per Seconds (cup/s)
Volumetric flow rate.
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
Liter per Seconds — sources
- BIPM SI Brochure — Litre and second as accepted units used together to express flow rate.

Frequently asked questions
How many liter per seconds are in 1 cup per seconds?
1 cup per seconds equals 0.2365882365 liter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cup per seconds to liter per seconds?
Multiply the cup per seconds value by 0.2365882365. The converter above does this instantly to whatever precision you set.
How do I convert liter per seconds back to cup per seconds?
Use the reverse factor: 1 liter per seconds equals 4.226752838 cup per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
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.
Is the cup per seconds to liter per seconds conversion exact?
Yes. Both cup per seconds and liter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.2365882365 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.
