About Converting Liter per Seconds to Pint per Years
Liter per Seconds and Pint 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
pint per years = liter per seconds × 66691718.2081
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 pint per years equals 1.499437e-11 base units, so dividing one by the other gives the direct liter per seconds-to-pint per years factor of 66691718.2081.
Simple example
1 L/s × 66691718.21 = 66,691,718.21 pt/yr
1 liter per seconds = 66,691,718.21 pint per years.
Real-world example
60 L/s × 66691718.21 = 4,001,503,092 pt/yr
60 liter per seconds = 4,001,503,092 pint per years.
Conversion table
| Liter per Seconds (L/s) | Pint per Years (pt/yr) |
|---|---|
| 0.1 L/s | 6,669,171.821 pt/yr |
| 1 L/s | 66,691,718.21 pt/yr |
| 10 L/s | 666,917,182.1 pt/yr |
| 60 L/s | 4,001,503,092 pt/yr |
| 100 L/s | 6,669,171,821 pt/yr |
| 1,000 L/s | 66,691,718,210 pt/yr |
Reverse conversion: Pint per Years to Liter per Seconds
1 pt/yr × 1.499437e-8 = 1.499437e-8 L/s
1 pint per years = 1.499437e-8 liter per seconds.
liter per seconds = pint per years × 1.499437e-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 pint per years are in 1 liter per seconds?
1 liter per seconds equals 66,691,718.21 pint per years, using the exact defined conversion factor rather than an estimate.
How do I convert liter per seconds to pint per years?
Multiply the liter per seconds value by 66691718.21. The converter above does this instantly to whatever precision you set.
How do I convert pint per years back to liter per seconds?
Use the reverse factor: 1 pint per years equals 1.499437e-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 pint per years?
Pint per Years (pt/yr) is a unit of flow rate.
Is the liter per seconds to pint per years conversion exact?
Yes. Both liter per seconds and pint per years are defined by fixed standards rather than physical artifacts, so the factor of 66691718.21 used above is exact to as many digits as you choose to display.
What is the difference between l/s vs. l/min?
