About Converting Gallon per Years to Cubic yard per Years
Gallon per Years and Cubic yard 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 yard per years = gallon per years × 0.00495113168724
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 yard per years equals 2.422778e-8 base units, so dividing one by the other gives the direct gallon per years-to-cubic yard per years factor of 0.00495113168724.
Simple example
1 gal/yr × 0.004951131687 = 0.0049511317 yd3/yr
1 gallon per years = 0.0049511317 cubic yard per years.
Real-world example
60 gal/yr × 0.004951131687 = 0.2970679012 yd3/yr
60 gallon per years = 0.2970679012 cubic yard per years.

Multiply the gallon per years value by 0.004951131687. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per years back to gallon per years?
Use the reverse factor: 1 cubic yard per years equals 201.974026 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 yard per years?
Cubic yard per Years (yd3/yr) is a unit of flow rate.
Is the gallon per years to cubic yard per years conversion exact?
Yes. Both gallon per years and cubic yard per years are defined by fixed standards rather than physical artifacts, so the factor of 0.004951131687 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.
