About Converting Gallon per Weeks to Cubic inch per Seconds
Gallon per Weeks 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 = gallon per weeks × 0.000381944444444
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per weeks equals 6.258948e-9 base units, and 1 cubic inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct gallon per weeks-to-cubic inch per seconds factor of 0.000381944444444.
Simple example
1 gal/wk × 0.0003819444444 = 0.0003819444 in3/s
1 gallon per weeks = 0.0003819444 cubic inch per seconds.
Real-world example
60 gal/wk × 0.0003819444444 = 0.0229166667 in3/s
60 gallon per weeks = 0.0229166667 cubic inch per seconds.

What is a gallon per weeks?
Gallon per Weeks (gal/wk) 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 gallon per weeks to cubic inch per seconds conversion exact?
Yes. Both gallon per weeks and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0003819444444 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.
