About Converting Gallon per Years to Fluid ounce per Years
Gallon per Years and Fluid ounce 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
fluid ounce per years = gallon per years × 128
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per years equals 1.199549e-10 base units, and 1 fluid ounce per years equals 9.371478e-13 base units, so dividing one by the other gives the direct gallon per years-to-fluid ounce per years factor of 128.
Simple example
1 gal/yr × 128 = 128 fl oz/yr
1 gallon per years = 128 fluid ounce per years.
Real-world example
60 gal/yr × 128 = 7,680 fl oz/yr
60 gallon per years = 7,680 fluid ounce per years.

Frequently asked questions
How many fluid ounce per years are in 1 gallon per years?
1 gallon per years equals 128 fluid ounce per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per years to fluid ounce per years?
Multiply the gallon per years value by 128. The converter above does this instantly to whatever precision you set.
How do I convert fluid ounce per years back to gallon per years?
Use the reverse factor: 1 fluid ounce per years equals 0.0078125 gallon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
What is a fluid ounce per years?
Fluid ounce per Years (fl oz/yr) is a unit of flow rate.
Is the gallon per years to fluid ounce per years conversion exact?
Yes. Both gallon per years and fluid ounce per years are defined by fixed standards rather than physical artifacts, so the factor of 128 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.
