About Converting Cubic yard per Days to Cubic foot per Years
Cubic yard per Days 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 = cubic yard per days × 9861.5475
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 cubic foot per years equals 8.973251e-10 base units, so dividing one by the other gives the direct cubic yard per days-to-cubic foot per years factor of 9861.5475.
Simple example
1 yd3/d × 9861.5475 = 9,861.5475 ft3/yr
1 cubic yard per days = 9,861.5475 cubic foot per years.
Real-world example
60 yd3/d × 9861.5475 = 591,692.85 ft3/yr
60 cubic yard per days = 591,692.85 cubic foot per years.

Multiply the cubic yard per days value by 9861.5475. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per years back to cubic yard per days?
Use the reverse factor: 1 cubic foot per years equals 0.000101404 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 cubic foot per years?
Cubic foot per Years (ft3/yr) is a unit of flow rate.
Is the cubic yard per days to cubic foot per years conversion exact?
Yes. Both cubic yard per days and cubic foot per years are defined by fixed standards rather than physical artifacts, so the factor of 9861.5475 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.
