About Converting Cubic inch per Years to Cubic foot per Days
Cubic inch per Years and Cubic foot 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 foot per days = cubic inch per years × 0.00000158443692534
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per years equals 5.192854e-13 base units, and 1 cubic foot per days equals 3.277413e-7 base units, so dividing one by the other gives the direct cubic inch per years-to-cubic foot per days factor of 0.00000158443692534.
Simple example
1 in3/yr × 0.000001584436925 = 0.0000015844 ft3/d
1 cubic inch per years = 0.0000015844 cubic foot per days.
Real-world example
60 in3/yr × 0.000001584436925 = 0.0000950662 ft3/d
60 cubic inch per years = 0.0000950662 cubic foot per days.

How do I convert cubic foot per days back to cubic inch per years?
Use the reverse factor: 1 cubic foot per days equals 631,139.04 cubic inch per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per years?
Cubic inch per Years (in3/yr) is a unit of flow rate.
What is a cubic foot per days?
Cubic foot per Days (ft3/d) is a unit of flow rate.
Is the cubic inch per years to cubic foot per days conversion exact?
Yes. Both cubic inch per years and cubic foot per days are defined by fixed standards rather than physical artifacts, so the factor of 0.000001584436925 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.
