About Converting Gallon per Minutes to Cup per Years
Gallon per Minutes and Cup per Years 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 years = gallon per minutes × 8415187.2
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 years equals 7.497183e-12 base units, so dividing one by the other gives the direct gallon per minutes-to-cup per years factor of 8415187.2.
Simple example
1 gal/min × 8415187.2 = 8,415,187.2 cup/yr
1 gallon per minutes = 8,415,187.2 cup per years.
Real-world example
60 gal/min × 8415187.2 = 504,911,232 cup/yr
60 gallon per minutes = 504,911,232 cup per years.

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 cup per years?
Cup per Years (cup/yr) is a unit of flow rate.
Is the gallon per minutes to cup per years conversion exact?
Yes. Both gallon per minutes and cup per years are defined by fixed standards rather than physical artifacts, so the factor of 8415187.2 used above is exact to as many digits as you choose to display.
Where is the gallon per minutes still used today?
United States (plumbing, pump, and irrigation industry standard)
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.
