About Converting Cubic inch per Seconds to Gallon per Weeks
Cubic inch per Seconds and Gallon 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
gallon per weeks = cubic inch per seconds × 2618.18181818
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 gallon per weeks equals 6.258948e-9 base units, so dividing one by the other gives the direct cubic inch per seconds-to-gallon per weeks factor of 2618.18181818.
Simple example
1 in3/s × 2618.181818 = 2,618.181818 gal/wk
1 cubic inch per seconds = 2,618.181818 gallon per weeks.
Real-world example
60 in3/s × 2618.181818 = 157,090.9091 gal/wk
60 cubic inch per seconds = 157,090.9091 gallon per weeks.

What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
What is a gallon per weeks?
Gallon per Weeks (gal/wk) is a unit of flow rate.
Is the cubic inch per seconds to gallon per weeks conversion exact?
Yes. Both cubic inch per seconds and gallon per weeks are defined by fixed standards rather than physical artifacts, so the factor of 2618.181818 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.
