About Converting Cubic foot per Days to Gallon per Years
Cubic foot per Days and Gallon 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
gallon per years = cubic foot per days × 2732.20363636
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 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct cubic foot per days-to-gallon per years factor of 2732.20363636.
Simple example
1 ft3/d × 2732.203636 = 2,732.203636 gal/yr
1 cubic foot per days = 2,732.203636 gallon per years.
Real-world example
60 ft3/d × 2732.203636 = 163,932.2182 gal/yr
60 cubic foot per days = 163,932.2182 gallon per years.

Multiply the cubic foot per days value by 2732.203636. The converter above does this instantly to whatever precision you set.
How do I convert gallon per years back to cubic foot per days?
Use the reverse factor: 1 gallon per years equals 0.0003660049 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 gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
Is the cubic foot per days to gallon per years conversion exact?
Yes. Both cubic foot per days and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 2732.203636 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.
