About Converting Imperial quart per Minutes to Liter per Seconds
Imperial quart per Minutes 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 = imperial quart per minutes × 0.0189420416667
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per minutes equals 0.0000189420416667 base units, and 1 liter per seconds equals 0.001 base units, so dividing one by the other gives the direct imperial quart per minutes-to-liter per seconds factor of 0.0189420416667.
Simple example
1 imp qt/min × 0.01894204167 = 0.0189420417 L/s
1 imperial quart per minutes = 0.0189420417 liter per seconds.
Real-world example
60 imp qt/min × 0.01894204167 = 1.1365225 L/s
60 imperial quart per minutes = 1.1365225 liter per seconds.

Understanding the Imperial quart per Minutes (imp qt/min)
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.

What is a imperial quart per minutes?
Imperial quart per Minutes (imp qt/min) 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 imperial quart per minutes to liter per seconds conversion exact?
Yes. Both imperial quart per minutes and liter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.01894204167 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.
