About Converting Cubic foot per Days to Liter per Years
Cubic foot 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 = cubic foot per days × 10342.5158414
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per days equals 3.277413e-7 base units, and 1 liter per years equals 3.168874e-11 base units, so dividing one by the other gives the direct cubic foot per days-to-liter per years factor of 10342.5158414.
Simple example
1 ft3/d × 10342.51584 = 10,342.51584 L/yr
1 cubic foot per days = 10,342.51584 liter per years.
Real-world example
60 ft3/d × 10342.51584 = 620,550.9505 L/yr
60 cubic foot per days = 620,550.9505 liter per years.

Frequently asked questions
How many liter per years are in 1 cubic foot per days?
1 cubic foot per days equals 10,342.51584 liter per years, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per days to liter per years?
Multiply the cubic foot per days value by 10342.51584. The converter above does this instantly to whatever precision you set.
How do I convert liter per years back to cubic foot per days?
Use the reverse factor: 1 liter per years equals 0.0000966883 cubic foot per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per days?
Cubic foot per Days (ft3/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 cubic foot per days to liter per years conversion exact?
Yes. Both cubic foot per days and liter per years are defined by fixed standards rather than physical artifacts, so the factor of 10342.51584 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.
