About Converting Imperial quart per Days to Liter per Seconds
Imperial quart per Days 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 days × 0.0000131541956019
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per days equals 1.31542e-8 base units, and 1 liter per seconds equals 0.001 base units, so dividing one by the other gives the direct imperial quart per days-to-liter per seconds factor of 0.0000131541956019.
Simple example
1 imp qt/d × 0.0000131541956 = 0.0000131542 L/s
1 imperial quart per days = 0.0000131542 liter per seconds.
Real-world example
60 imp qt/d × 0.0000131541956 = 0.0007892517 L/s
60 imperial quart per days = 0.0007892517 liter per seconds.

Understanding the Imperial quart per Days (imp qt/d)
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

Frequently asked questions
How many liter per seconds are in 1 imperial quart per days?
1 imperial quart per days equals 0.0000131542 liter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per days to liter per seconds?
Multiply the imperial quart per days value by 0.0000131541956. The converter above does this instantly to whatever precision you set.
How do I convert liter per seconds back to imperial quart per days?
Use the reverse factor: 1 liter per seconds equals 76,021.37221 imperial quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per days?
Imperial quart per Days (imp qt/d) 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 days to liter per seconds conversion exact?
Yes. Both imperial quart per days and liter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0000131541956 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.
