About Converting Liter per Days to Cubic foot per Years
Liter per Days and Cubic foot 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
cubic foot per years = liter per days × 12.89841716
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per days equals 1.157407e-8 base units, and 1 cubic foot per years equals 8.973251e-10 base units, so dividing one by the other gives the direct liter per days-to-cubic foot per years factor of 12.89841716.
Simple example
1 L/d × 12.89841716 = 12.89841716 ft3/yr
1 liter per days = 12.89841716 cubic foot per years.
Real-world example
60 L/d × 12.89841716 = 773.9050296 ft3/yr
60 liter per days = 773.9050296 cubic foot per years.

Frequently asked questions
How many cubic foot per years are in 1 liter per days?
1 liter per days equals 12.89841716 cubic foot per years, using the exact defined conversion factor rather than an estimate.
How do I convert liter per days to cubic foot per years?
Multiply the liter per days value by 12.89841716. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per years back to liter per days?
Use the reverse factor: 1 cubic foot per years equals 0.0775288927 liter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per days?
Liter per Days (L/d) is a unit of flow rate.
What is a cubic foot per years?
Cubic foot per Years (ft3/yr) is a unit of flow rate.
Is the liter per days to cubic foot per years conversion exact?
Yes. Both liter per days and cubic foot per years are defined by fixed standards rather than physical artifacts, so the factor of 12.89841716 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.
