About Converting Liter per Seconds to Cubic Meters per Millisecond
Liter per Seconds and Cubic Meter 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
cubic meters per millisecond = liter per seconds × 0.000001
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 cubic meter per millisecond equals 1000 base units, so dividing one by the other gives the direct liter per seconds-to-cubic meter per millisecond factor of 0.000001.
Simple example
1 L/s × 0.000001 = 0.000001 m3/ms
1 liter per seconds = 0.000001 cubic meters per millisecond.
Real-world example
60 L/s × 0.000001 = 0.00006 m3/ms
60 liter per seconds = 0.00006 cubic meters per millisecond.
Conversion table
| Liter per Seconds (L/s) | Cubic Meter per Millisecond (m3/ms) |
|---|---|
| 0.1 L/s | 1e-7 m3/ms |
| 1 L/s | 0.000001 m3/ms |
| 10 L/s | 0.00001 m3/ms |
| 60 L/s | 0.00006 m3/ms |
| 100 L/s | 0.0001 m3/ms |
| 1,000 L/s | 0.001 m3/ms |
Reverse conversion: Cubic Meter per Millisecond to Liter per Seconds
0.000001 m3/ms × 1000000 = 1 L/s
0.000001 cubic meters per millisecond = 1 liter per seconds.
liter per seconds = cubic meters per millisecond × 1000000

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 cubic meters per millisecond are in 1 liter per seconds?
1 liter per seconds equals 0.000001 cubic meters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert liter per seconds to cubic meter per millisecond?
Multiply the liter per seconds value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per millisecond back to liter per seconds?
Use the reverse factor: 1 cubic meter per millisecond equals 1,000,000 liter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
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.
What is a cubic meter per millisecond?
Cubic Meter per Millisecond (m3/ms) is a unit of flow rate.
Is the liter per seconds to cubic meter per millisecond conversion exact?
Yes. Both liter per seconds and cubic meter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 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.
Where is the liter per seconds still used today?
Common in municipal water-utility and industrial flow specifications internationally
