About Converting Cup per Hours to Cubic inch per Days
Cup per Hours 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 = cup per hours × 346.5
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per hours equals 6.571895e-8 base units, and 1 cubic inch per days equals 1.896651e-10 base units, so dividing one by the other gives the direct cup per hours-to-cubic inch per days factor of 346.5.
Simple example
1 cup/h × 346.5 = 346.5 in3/d
1 cup per hours = 346.5 cubic inch per days.
Real-world example
60 cup/h × 346.5 = 20,790 in3/d
60 cup per hours = 20,790 cubic inch per days.

Frequently asked questions
How many cubic inch per days are in 1 cup per hours?
1 cup per hours equals 346.5 cubic inch per days, using the exact defined conversion factor rather than an estimate.
How do I convert cup per hours to cubic inch per days?
Multiply the cup per hours value by 346.5. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per days back to cup per hours?
Use the reverse factor: 1 cubic inch per days equals 0.0028860029 cup per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per hours?
Cup per Hours (cup/h) 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 cup per hours to cubic inch per days conversion exact?
Yes. Both cup per hours and cubic inch per days are defined by fixed standards rather than physical artifacts, so the factor of 346.5 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.
