About Converting Imperial quarts per Millisecond to Liter per Seconds
Imperial quart per Millisecond 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 quarts per millisecond × 1136.5225
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per millisecond equals 1.1365225 base units, and 1 liter per seconds equals 0.001 base units, so dividing one by the other gives the direct imperial quart per millisecond-to-liter per seconds factor of 1136.5225.
Simple example
1 imp qt/ms × 1136.5225 = 1,136.5225 L/s
1 imperial quart per millisecond = 1,136.5225 liter per seconds.
Real-world example
60 imp qt/ms × 1136.5225 = 68,191.35 L/s
60 imperial quarts per millisecond = 68,191.35 liter per seconds.

Understanding the Imperial quart per Millisecond (imp qt/ms)
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.

Frequently asked questions
How many liter per seconds are in 1 imperial quart per millisecond?
1 imperial quart per millisecond equals 1,136.5225 liter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per millisecond to liter per seconds?
Multiply the imperial quart per millisecond value by 1136.5225. The converter above does this instantly to whatever precision you set.
How do I convert liter per seconds back to imperial quart per millisecond?
Use the reverse factor: 1 liter per seconds equals 0.000879877 imperial quarts per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per millisecond?
Imperial quart per Millisecond (imp qt/ms) 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 millisecond to liter per seconds conversion exact?
Yes. Both imperial quart per millisecond and liter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1136.5225 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.
