About Converting Cup per Seconds to Cubic inch per Weeks
Cup per Seconds and Cubic inch per Weeks 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 weeks = cup per seconds × 8731800
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per seconds equals 0.0002365882365 base units, and 1 cubic inch per weeks equals 2.709501e-11 base units, so dividing one by the other gives the direct cup per seconds-to-cubic inch per weeks factor of 8731800.
Simple example
1 cup/s × 8731800 = 8,731,800 in3/wk
1 cup per seconds = 8,731,800 cubic inch per weeks.
Real-world example
60 cup/s × 8731800 = 523,908,000 in3/wk
60 cup per seconds = 523,908,000 cubic inch per weeks.

Frequently asked questions
How many cubic inch per weeks are in 1 cup per seconds?
1 cup per seconds equals 8,731,800 cubic inch per weeks, using the exact defined conversion factor rather than an estimate.
How do I convert cup per seconds to cubic inch per weeks?
Multiply the cup per seconds value by 8731800. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per weeks back to cup per seconds?
Use the reverse factor: 1 cubic inch per weeks equals 1.145239e-7 cup per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
What is a cubic inch per weeks?
Cubic inch per Weeks (in3/wk) is a unit of flow rate.
Is the cup per seconds to cubic inch per weeks conversion exact?
Yes. Both cup per seconds and cubic inch per weeks are defined by fixed standards rather than physical artifacts, so the factor of 8731800 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.
