About Converting Cup per Days to Cubic inch per Seconds
Cup per Days and Cubic inch per Seconds 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 seconds = cup per days × 0.000167100694444
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per days equals 2.73829e-9 base units, and 1 cubic inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct cup per days-to-cubic inch per seconds factor of 0.000167100694444.
Simple example
1 cup/d × 0.0001671006944 = 0.0001671007 in3/s
1 cup per days = 0.0001671007 cubic inch per seconds.
Real-world example
60 cup/d × 0.0001671006944 = 0.0100260417 in3/s
60 cup per days = 0.0100260417 cubic inch per seconds.

Multiply the cup per days value by 0.0001671006944. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per seconds back to cup per days?
Use the reverse factor: 1 cubic inch per seconds equals 5,984.415584 cup per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
Is the cup per days to cubic inch per seconds conversion exact?
Yes. Both cup per days and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0001671006944 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.
