About Converting Fluid ounce per Days to Gallon per Years
Fluid ounce 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 = fluid ounce per days × 2.85345703125
This factor comes from each unit's defined relationship to the category's base unit: 1 fluid ounce per days equals 3.422862e-10 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct fluid ounce per days-to-gallon per years factor of 2.85345703125.
Simple example
1 fl oz/d × 2.853457031 = 2.853457031 gal/yr
1 fluid ounce per days = 2.853457031 gallon per years.
Real-world example
60 fl oz/d × 2.853457031 = 171.2074219 gal/yr
60 fluid ounce per days = 171.2074219 gallon per years.

What is a fluid ounce per days?
Fluid ounce per Days (fl oz/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 fluid ounce per days to gallon per years conversion exact?
Yes. Both fluid ounce per days and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 2.853457031 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.
