About Converting Gallon per Years to Cubic foot per Years
Gallon per Years 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 years × 0.133680555556
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 cubic foot per years equals 8.973251e-10 base units, so dividing one by the other gives the direct gallon per years-to-cubic foot per years factor of 0.133680555556.
Simple example
1 gal/yr × 0.1336805556 = 0.1336805556 ft3/yr
1 gallon per years = 0.1336805556 cubic foot per years.
Real-world example
60 gal/yr × 0.1336805556 = 8.020833333 ft3/yr
60 gallon per years = 8.020833333 cubic foot per years.

Multiply the gallon per years value by 0.1336805556. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per years back to gallon per years?
Use the reverse factor: 1 cubic foot per years equals 7.480519481 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 cubic foot per years?
Cubic foot per Years (ft3/yr) is a unit of flow rate.
Is the gallon per years to cubic foot per years conversion exact?
Yes. Both gallon per years and cubic foot per years are defined by fixed standards rather than physical artifacts, so the factor of 0.1336805556 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.
