About Converting Milliliter per Hours to Liter per Seconds
Milliliter per Hours 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 hours × 2.777778e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per hours equals 2.777778e-10 base units, and 1 liter per seconds equals 0.001 base units, so dividing one by the other gives the direct milliliter per hours-to-liter per seconds factor of 2.777778e-7.
Simple example
1 mL/h × 2.777778e-7 = 2.777778e-7 L/s
1 milliliter per hours = 2.777778e-7 liter per seconds.
Real-world example
60 mL/h × 2.777778e-7 = 0.0000166667 L/s
60 milliliter per hours = 0.0000166667 liter per seconds.
Conversion table

Reverse conversion: Liter per Seconds to Milliliter per Hours
2.777778e-7 L/s × 3600000 = 1.00000008 mL/h
2.777778e-7 liter per seconds = 1.00000008 milliliter per hours.
milliliter per hours = liter per seconds × 3600000

Understanding the Milliliter per Hours (mL/h)
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 milliliter per hours?
1 milliliter per hours equals 2.777778e-7 liter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per hours to liter per seconds?
Multiply the milliliter per hours value by 2.777778e-7. The converter above does this instantly to whatever precision you set.
How do I convert liter per seconds back to milliliter per hours?
Use the reverse factor: 1 liter per seconds equals 3,600,000 milliliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per hours?
Milliliter per Hours (mL/h) 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 hours to liter per seconds conversion exact?
Yes. Both milliliter per hours and liter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 2.777778e-7 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.
