About Converting Gallon per Years to Liter per Seconds
Gallon 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 = gallon per years × 1.199549e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per years equals 1.199549e-10 base units, and 1 liter per seconds equals 0.001 base units, so dividing one by the other gives the direct gallon per years-to-liter per seconds factor of 1.199549e-7.
Simple example
1 gal/yr × 1.199549e-7 = 1.199549e-7 L/s
1 gallon per years = 1.199549e-7 liter per seconds.
Real-world example
60 gal/yr × 1.199549e-7 = 0.0000071973 L/s
60 gallon per years = 0.0000071973 liter per seconds.

Understanding the Gallon per Years (gal/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
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 gallon per years?
1 gallon per years equals 1.199549e-7 liter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per years to liter per seconds?
Multiply the gallon per years value by 1.199549e-7. The converter above does this instantly to whatever precision you set.
How do I convert liter per seconds back to gallon per years?
Use the reverse factor: 1 liter per seconds equals 8,336,464.776 gallon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per years?
Gallon per Years (gal/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 gallon per years to liter per seconds conversion exact?
Yes. Both gallon per years and liter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1.199549e-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.
