About Converting Fluid ounce per Years to Gallon per Days
Fluid ounce per Years and Gallon per Days 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 days = fluid ounce per years × 0.0000213898984921
This factor comes from each unit's defined relationship to the category's base unit: 1 fluid ounce per years equals 9.371478e-13 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct fluid ounce per years-to-gallon per days factor of 0.0000213898984921.
Simple example
1 fl oz/yr × 0.00002138989849 = 0.0000213899 gal/d
1 fluid ounce per years = 0.0000213899 gallon per days.
Real-world example
60 fl oz/yr × 0.00002138989849 = 0.0012833939 gal/d
60 fluid ounce per years = 0.0012833939 gallon per days.

What is a fluid ounce per years?
Fluid ounce per Years (fl oz/yr) is a unit of flow rate.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
Is the fluid ounce per years to gallon per days conversion exact?
Yes. Both fluid ounce per years and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 0.00002138989849 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.
