About Converting Gallon per Minutes to Cup per Weeks
Gallon per Minutes 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. Gallon per Minutes is most often used for us residential and commercial plumbing fixture flow ratings.
Formula
cup per weeks = gallon per minutes × 161280
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per minutes equals 0.0000630901964 base units, and 1 cup per weeks equals 3.911843e-10 base units, so dividing one by the other gives the direct gallon per minutes-to-cup per weeks factor of 161280.
Simple example
1 gal/min × 161280 = 161,280 cup/wk
1 gallon per minutes = 161,280 cup per weeks.
Real-world example
60 gal/min × 161280 = 9,676,800 cup/wk
60 gallon per minutes = 9,676,800 cup per weeks.

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.
