Volumetric flow rate.
Milliliter per Seconds to Liter per Seconds Converter — mL/s to L/s
Convert Milliliter per Seconds (mL/s) to Liter per Seconds (L/s) using the exact conversion factor (1 milliliter per seconds = 0.001 liter per seconds). See the formula, worked examples, conversion table, and common uses.

About Converting Milliliter per Seconds to Liter per Seconds
Milliliter per Seconds 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 = milliliter per seconds × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per seconds equals 0.000001 base units, and 1 liter per seconds equals 0.001 base units, so dividing one by the other gives the direct milliliter per seconds-to-liter per seconds factor of 0.001.
Simple example
1 mL/s × 0.001 = 0.001 L/s
1 milliliter per seconds = 0.001 liter per seconds.
Real-world example
60 mL/s × 0.001 = 0.06 L/s
60 milliliter per seconds = 0.06 liter per seconds.
Conversion table
| Milliliter per Seconds (mL/s) | Liter per Seconds (L/s) |
|---|---|
| 0.1 mL/s | 0.0001 L/s |
| 1 mL/s | 0.001 L/s |
| 10 mL/s | 0.01 L/s |
| 60 mL/s | 0.06 L/s |
| 100 mL/s | 0.1 L/s |
| 1,000 mL/s | 1 L/s |
Reverse conversion: Liter per Seconds to Milliliter per Seconds
0.001 L/s × 1000 = 1 mL/s
0.001 liter per seconds = 1 milliliter per seconds.
milliliter per seconds = liter per seconds × 1000

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

- 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 milliliter per seconds?
1 milliliter per seconds equals 0.001 liter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per seconds to liter per seconds?
Multiply the milliliter per seconds value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert liter per seconds back to milliliter per seconds?
Use the reverse factor: 1 liter per seconds equals 1,000 milliliter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per seconds?
Milliliter per Seconds (mL/s) 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 milliliter per seconds to liter per seconds conversion exact?
Yes. Both milliliter per seconds and liter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
