About Converting Quart per Days to Liter per Seconds
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 = quart per days × 0.0000109531590972
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per days equals 1.095316e-8 base units, and 1 liter per seconds equals 0.001 base units, so dividing one by the other gives the direct quart per days-to-liter per seconds factor of 0.0000109531590972.
Simple example
1 qt/d × 0.0000109531591 = 0.0000109532 L/s
1 quart per days = 0.0000109532 liter per seconds.
Real-world example
60 qt/d × 0.0000109531591 = 0.0006571895 L/s
60 quart per days = 0.0006571895 liter per seconds.

Reverse conversion: Liter per Seconds to Quart per Days
0.0000109532 L/s × 91297.86129 = 1.000003734 qt/d
0.0000109532 liter per seconds = 1.000003734 quart per days.
quart per days = liter per seconds × 91297.861295

Understanding the Quart per Days (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 quart per days?
1 quart per days equals 0.0000109532 liter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert quart per days to liter per seconds?
Multiply the quart per days value by 0.0000109531591. The converter above does this instantly to whatever precision you set.
How do I convert liter per seconds back to quart per days?
Use the reverse factor: 1 liter per seconds equals 91,297.86129 quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per days?
Quart per Days (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 quart per days to liter per seconds conversion exact?
Yes. Both quart per days and liter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0000109531591 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.
