About Converting Cubic inch per Seconds to Cup per Days
Cubic inch per Seconds 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 seconds × 5984.41558442
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per seconds equals 0.000016387064 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 seconds-to-cup per days factor of 5984.41558442.
Simple example
1 in3/s × 5984.415584 = 5,984.415584 cup/d
1 cubic inch per seconds = 5,984.415584 cup per days.
Real-world example
60 in3/s × 5984.415584 = 359,064.9351 cup/d
60 cubic inch per seconds = 359,064.9351 cup per days.

Multiply the cubic inch per seconds value by 5984.415584. The converter above does this instantly to whatever precision you set.
How do I convert cup per days back to cubic inch per seconds?
Use the reverse factor: 1 cup per days equals 0.0001671007 cubic inch per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) 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 seconds to cup per days conversion exact?
Yes. Both cubic inch per seconds and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 5984.415584 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.
