About Converting Liter per Seconds to Quart per Seconds
Liter per Seconds and Quart 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. Liter per Seconds is most often used for municipal water supply and treatment plant flow rates.
Formula
quart per seconds = liter per seconds × 1.05668820943
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 quart per seconds equals 0.000946352946 base units, so dividing one by the other gives the direct liter per seconds-to-quart per seconds factor of 1.05668820943.
Simple example
1 L/s × 1.056688209 = 1.056688209 qt/s
1 liter per seconds = 1.056688209 quart per seconds.
Real-world example
60 L/s × 1.056688209 = 63.40129257 qt/s
60 liter per seconds = 63.40129257 quart per seconds.

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
