About Converting Cubic yard per Days to Gallon per Years
Cubic yard per Days and Gallon 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
gallon per years = cubic yard per days × 73769.4981818
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard per days equals 0.00000884901456 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct cubic yard per days-to-gallon per years factor of 73769.4981818.
Simple example
1 yd3/d × 73769.49818 = 73,769.49818 gal/yr
1 cubic yard per days = 73,769.49818 gallon per years.
Real-world example
60 yd3/d × 73769.49818 = 4,426,169.891 gal/yr
60 cubic yard per days = 4,426,169.891 gallon per years.

Multiply the cubic yard per days value by 73769.49818. The converter above does this instantly to whatever precision you set.
How do I convert gallon per years back to cubic yard per days?
Use the reverse factor: 1 gallon per years equals 0.0000135557 cubic yard per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic yard per days?
Cubic yard per Days (yd3/d) is a unit of flow rate.
What is a gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
Is the cubic yard per days to gallon per years conversion exact?
Yes. Both cubic yard per days and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 73769.49818 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.
