About Converting Cubic foot per Years to Liter per Years
Cubic foot per Years 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 years × 28.316846592
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per years equals 8.973251e-10 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 years-to-liter per years factor of 28.316846592.
Simple example
1 ft3/yr × 28.31684659 = 28.31684659 L/yr
1 cubic foot per years = 28.31684659 liter per years.
Real-world example
60 ft3/yr × 28.31684659 = 1,699.010796 L/yr
60 cubic foot per years = 1,699.010796 liter per years.

Frequently asked questions
How many liter per years are in 1 cubic foot per years?
1 cubic foot per years equals 28.31684659 liter per years, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per years to liter per years?
Multiply the cubic foot per years value by 28.31684659. The converter above does this instantly to whatever precision you set.
How do I convert liter per years back to cubic foot per years?
Use the reverse factor: 1 liter per years equals 0.0353146667 cubic foot per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per years?
Cubic foot per Years (ft3/yr) 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 years to liter per years conversion exact?
Yes. Both cubic foot per years and liter per years are defined by fixed standards rather than physical artifacts, so the factor of 28.31684659 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.
