About Converting Cubic inch per Seconds to Cup per Weeks
Cubic inch per Seconds and Cup 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
cup per weeks = cubic inch per seconds × 41890.9090909
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 weeks equals 3.911843e-10 base units, so dividing one by the other gives the direct cubic inch per seconds-to-cup per weeks factor of 41890.9090909.
Simple example
1 in3/s × 41890.90909 = 41,890.90909 cup/wk
1 cubic inch per seconds = 41,890.90909 cup per weeks.
Real-world example
60 in3/s × 41890.90909 = 2,513,454.545 cup/wk
60 cubic inch per seconds = 2,513,454.545 cup per weeks.

What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
What is a cup per weeks?
Cup per Weeks (cup/wk) is a unit of flow rate.
Is the cubic inch per seconds to cup per weeks conversion exact?
Yes. Both cubic inch per seconds and cup per weeks are defined by fixed standards rather than physical artifacts, so the factor of 41890.90909 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.
