About Converting Liter per Seconds to Cubic Kilometers per Millisecond
Liter per Seconds and Cubic Kilometer 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 kilometers per millisecond = liter per seconds × 1e-15
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 kilometer per millisecond equals 1e+12 base units, so dividing one by the other gives the direct liter per seconds-to-cubic kilometer per millisecond factor of 1e-15.
Simple example
1 L/s × 1e-15 = 1e-15 km3/ms
1 liter per seconds = 1e-15 cubic kilometers per millisecond.
Real-world example
60 L/s × 1e-15 = 6e-14 km3/ms
60 liter per seconds = 6e-14 cubic kilometers per millisecond.
Conversion table
| Liter per Seconds (L/s) | Cubic Kilometer per Millisecond (km3/ms) |
|---|---|
| 0.1 L/s | 1e-16 km3/ms |
| 1 L/s | 1e-15 km3/ms |
| 10 L/s | 1e-14 km3/ms |
| 60 L/s | 6e-14 km3/ms |
| 100 L/s | 1e-13 km3/ms |
| 1,000 L/s | 1e-12 km3/ms |
Reverse conversion: Cubic Kilometer per Millisecond to Liter per Seconds
1e-15 km3/ms × 1e+15 = 1 L/s
1e-15 cubic kilometers per millisecond = 1 liter per seconds.
liter per seconds = cubic kilometers per millisecond × 1e+15

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 kilometers per millisecond are in 1 liter per seconds?
1 liter per seconds equals 1e-15 cubic kilometers per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert liter per seconds to cubic kilometer per millisecond?
Multiply the liter per seconds value by 1e-15. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per millisecond back to liter per seconds?
Use the reverse factor: 1 cubic kilometer per millisecond equals 1e+15 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 kilometer per millisecond?
Cubic Kilometer per Millisecond (km3/ms) is a unit of flow rate.
Is the liter per seconds to cubic kilometer per millisecond conversion exact?
Yes. Both liter per seconds and cubic kilometer per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1e-15 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
