About Converting Quart per Days to Liter per Years
Quart per Days 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. Both are volumetric flow rate units.
Formula
liter per years = quart per days × 345.648315879
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per days equals 1.095316e-8 base units, and 1 liter per years equals 3.168874e-11 base units, so dividing one by the other gives the direct quart per days-to-liter per years factor of 345.648315879.
Simple example
1 qt/d × 345.6483159 = 345.6483159 L/yr
1 quart per days = 345.6483159 liter per years.
Real-world example
60 qt/d × 345.6483159 = 20,738.89895 L/yr
60 quart per days = 20,738.89895 liter per years.

Frequently asked questions
How many liter per years are in 1 quart per days?
1 quart per days equals 345.6483159 liter per years, using the exact defined conversion factor rather than an estimate.
How do I convert quart per days to liter per years?
Multiply the quart per days value by 345.6483159. The converter above does this instantly to whatever precision you set.
How do I convert liter per years back to quart per days?
Use the reverse factor: 1 liter per years equals 0.0028931141 quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
What is a liter per years?
Liter per Years (L/yr) is a unit of flow rate.
Is the quart per days to liter per years conversion exact?
Yes. Both quart per days and liter per years are defined by fixed standards rather than physical artifacts, so the factor of 345.6483159 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.
