About Converting Liter per Seconds to Liter per Years
Liter per Seconds and Liter per Years 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
liter per years = liter per seconds × 31556952
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 liter per years equals 3.168874e-11 base units, so dividing one by the other gives the direct liter per seconds-to-liter per years factor of 31556952.
Simple example
1 L/s × 31556952 = 31,556,952 L/yr
1 liter per seconds = 31,556,952 liter per years.
Real-world example
60 L/s × 31556952 = 1,893,417,120 L/yr
60 liter per seconds = 1,893,417,120 liter per years.
Conversion table
| Liter per Seconds (L/s) | Liter per Years (L/yr) |
|---|---|
| 0.1 L/s | 3,155,695.2 L/yr |
| 1 L/s | 31,556,952 L/yr |
| 10 L/s | 315,569,520 L/yr |
| 60 L/s | 1,893,417,120 L/yr |
| 100 L/s | 3,155,695,200 L/yr |
| 1,000 L/s | 31,556,952,000 L/yr |
Reverse conversion: Liter per Years to Liter per Seconds
1 L/yr × 3.168874e-8 = 3.168874e-8 L/s
1 liter per years = 3.168874e-8 liter per seconds.
liter per seconds = liter per years × 3.168874e-8

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

Frequently asked questions
How many liter per years are in 1 liter per seconds?
1 liter per seconds equals 31,556,952 liter per years, using the exact defined conversion factor rather than an estimate.
How do I convert liter per seconds to liter per years?
Multiply the liter per seconds value by 31556952. The converter above does this instantly to whatever precision you set.
How do I convert liter per years back to liter per seconds?
Use the reverse factor: 1 liter per years equals 3.168874e-8 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 liter per years?
Liter per Years (L/yr) is a unit of flow rate.
Is the liter per seconds to liter per years conversion exact?
Yes. Both liter per seconds and liter per years are defined by fixed standards rather than physical artifacts, so the factor of 31556952 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.
