About Converting Gallon per Years to Cubic yard per Days
Gallon per Years and Cubic yard 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
cubic yard per days = gallon per years × 0.000013555738139
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 days equals 0.00000884901456 base units, so dividing one by the other gives the direct gallon per years-to-cubic yard per days factor of 0.000013555738139.
Simple example
1 gal/yr × 0.00001355573814 = 0.0000135557 yd3/d
1 gallon per years = 0.0000135557 cubic yard per days.
Real-world example
60 gal/yr × 0.00001355573814 = 0.0008133443 yd3/d
60 gallon per years = 0.0008133443 cubic yard per days.

How do I convert cubic yard per days back to gallon per years?
Use the reverse factor: 1 cubic yard per days equals 73,769.49818 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 days?
Cubic yard per Days (yd3/d) is a unit of flow rate.
Is the gallon per years to cubic yard per days conversion exact?
Yes. Both gallon per years and cubic yard per days are defined by fixed standards rather than physical artifacts, so the factor of 0.00001355573814 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.
