About Converting Liter per Seconds to Quart per Hours
Liter per Seconds and Quart per Hours 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 hours = liter per seconds × 3804.07755396
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 hours equals 2.628758e-7 base units, so dividing one by the other gives the direct liter per seconds-to-quart per hours factor of 3804.07755396.
Simple example
1 L/s × 3804.077554 = 3,804.077554 qt/h
1 liter per seconds = 3,804.077554 quart per hours.
Real-world example
60 L/s × 3804.077554 = 228,244.6532 qt/h
60 liter per seconds = 228,244.6532 quart per hours.
Conversion table

Reverse conversion: Quart per Hours to Liter per Seconds
1 qt/h × 0.0002628758183 = 0.0002628758 L/s
1 quart per hours = 0.0002628758 liter per seconds.
liter per seconds = quart per hours × 0.000262875818333

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
