About Converting Liter per Seconds to Imperial quarts per Millisecond
Liter per Seconds and Imperial quart per Millisecond 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
imperial quarts per millisecond = liter per seconds × 0.000879876993196
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 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct liter per seconds-to-imperial quart per millisecond factor of 0.000879876993196.
Simple example
1 L/s × 0.0008798769932 = 0.000879877 imp qt/ms
1 liter per seconds = 0.000879877 imperial quarts per millisecond.
Real-world example
60 L/s × 0.0008798769932 = 0.0527926196 imp qt/ms
60 liter per seconds = 0.0527926196 imperial quarts per millisecond.

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
