About Converting Cubic inch per Years to Cup per Days
Cubic inch per Years and Cup 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
cup per days = cubic inch per years × 0.000189638580571
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 cup per days equals 2.73829e-9 base units, so dividing one by the other gives the direct cubic inch per years-to-cup per days factor of 0.000189638580571.
Simple example
1 in3/yr × 0.0001896385806 = 0.0001896386 cup/d
1 cubic inch per years = 0.0001896386 cup per days.
Real-world example
60 in3/yr × 0.0001896385806 = 0.0113783148 cup/d
60 cubic inch per years = 0.0113783148 cup per days.

What is a cubic inch per years?
Cubic inch per Years (in3/yr) is a unit of flow rate.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
Is the cubic inch per years to cup per days conversion exact?
Yes. Both cubic inch per years and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 0.0001896385806 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.
