About Converting Gallon per Days to Cubic foot per Years
Gallon 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 = gallon per days × 48.8258203125
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 cubic foot per years equals 8.973251e-10 base units, so dividing one by the other gives the direct gallon per days-to-cubic foot per years factor of 48.8258203125.
Simple example
1 gal/d × 48.82582031 = 48.82582031 ft3/yr
1 gallon per days = 48.82582031 cubic foot per years.
Real-world example
60 gal/d × 48.82582031 = 2,929.549219 ft3/yr
60 gallon per days = 2,929.549219 cubic foot per years.

How do I convert cubic foot per years back to gallon per days?
Use the reverse factor: 1 cubic foot per years equals 0.0204809667 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/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 gallon per days to cubic foot per years conversion exact?
Yes. Both gallon per days and cubic foot per years are defined by fixed standards rather than physical artifacts, so the factor of 48.82582031 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.
