About Converting Gallon per Minutes to Quart per Weeks
Gallon per Minutes and Quart 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
quart per weeks = gallon per minutes × 40320
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 quart per weeks equals 1.564737e-9 base units, so dividing one by the other gives the direct gallon per minutes-to-quart per weeks factor of 40320.
Simple example
1 gal/min × 40320 = 40,320 qt/wk
1 gallon per minutes = 40,320 quart per weeks.
Real-world example
60 gal/min × 40320 = 2,419,200 qt/wk
60 gallon per minutes = 2,419,200 quart per weeks.

What is a gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
What is a quart 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.
