About Converting Cubic foot per Years to Cubic inch per Days
Cubic foot per Years and Cubic inch 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 inch per days = cubic foot per years × 4.73110330808
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per years equals 8.973251e-10 base units, and 1 cubic inch per days equals 1.896651e-10 base units, so dividing one by the other gives the direct cubic foot per years-to-cubic inch per days factor of 4.73110330808.
Simple example
1 ft3/yr × 4.731103308 = 4.731103308 in3/d
1 cubic foot per years = 4.731103308 cubic inch per days.
Real-world example
60 ft3/yr × 4.731103308 = 283.8661985 in3/d
60 cubic foot per years = 283.8661985 cubic inch per days.

What is a cubic foot per years?
Cubic foot per Years (ft3/yr) is a unit of flow rate.
What is a cubic inch per days?
Cubic inch per Days (in3/d) is a unit of flow rate.
Is the cubic foot per years to cubic inch per days conversion exact?
Yes. Both cubic foot per years and cubic inch per days are defined by fixed standards rather than physical artifacts, so the factor of 4.731103308 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.
