About Converting Cubic Meter per Years to Liter per Seconds
Cubic Meter per Years 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 = cubic meter per years × 0.0000316887385068
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per years equals 3.168874e-8 base units, and 1 liter per seconds equals 0.001 base units, so dividing one by the other gives the direct cubic meter per years-to-liter per seconds factor of 0.0000316887385068.
Simple example
1 m3/yr × 0.00003168873851 = 0.0000316887 L/s
1 cubic meter per years = 0.0000316887 liter per seconds.
Real-world example
60 m3/yr × 0.00003168873851 = 0.0019013243 L/s
60 cubic meter per years = 0.0019013243 liter per seconds.

Understanding the Cubic Meter per Years (m3/yr)
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

Frequently asked questions
How many liter per seconds are in 1 cubic meter per years?
1 cubic meter per years equals 0.0000316887 liter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per years to liter per seconds?
Multiply the cubic meter per years value by 0.00003168873851. The converter above does this instantly to whatever precision you set.
How do I convert liter per seconds back to cubic meter per years?
Use the reverse factor: 1 liter per seconds equals 31,556.952 cubic meter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per years?
Cubic Meter per Years (m3/yr) 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 cubic meter per years to liter per seconds conversion exact?
Yes. Both cubic meter per years and liter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.00003168873851 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.
