About Converting Liter per Years to Quart per Seconds
Liter per Years and Quart 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
quart per seconds = liter per years × 3.348512e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per years equals 3.168874e-11 base units, and 1 quart per seconds equals 0.000946352946 base units, so dividing one by the other gives the direct liter per years-to-quart per seconds factor of 3.348512e-8.
Simple example
1 L/yr × 3.348512e-8 = 3.348512e-8 qt/s
1 liter per years = 3.348512e-8 quart per seconds.
Real-world example
60 L/yr × 3.348512e-8 = 0.0000020091 qt/s
60 liter per years = 0.0000020091 quart per seconds.

Frequently asked questions
How many quart per seconds are in 1 liter per years?
1 liter per years equals 3.348512e-8 quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert liter per years to quart per seconds?
Multiply the liter per years value by 3.348512e-8. The converter above does this instantly to whatever precision you set.
How do I convert quart per seconds back to liter per years?
Use the reverse factor: 1 quart per seconds equals 29,864,014.49 liter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per years?
Liter per Years (L/yr) is a unit of flow rate.
What is a quart per seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
Is the liter per years to quart per seconds conversion exact?
Yes. Both liter per years and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 3.348512e-8 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
