About Converting Imperial gallon per Hours to Cup per Years
Imperial gallon per Hours 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. Both are volumetric flow rate units.
Formula
cup per years = imperial gallon per hours × 168436.974016
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per hours equals 0.00000126280277778 base units, and 1 cup per years equals 7.497183e-12 base units, so dividing one by the other gives the direct imperial gallon per hours-to-cup per years factor of 168436.974016.
Simple example
1 imp gal/h × 168436.974 = 168,436.974 cup/yr
1 imperial gallon per hours = 168,436.974 cup per years.
Real-world example
60 imp gal/h × 168436.974 = 10,106,218.44 cup/yr
60 imperial gallon per hours = 10,106,218.44 cup per years.

What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
What is a cup per years?
Cup per Years (cup/yr) is a unit of flow rate.
Is the imperial gallon per hours to cup per years conversion exact?
Yes. Both imperial gallon per hours and cup per years are defined by fixed standards rather than physical artifacts, so the factor of 168436.974 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.
