About Converting Gallon per Minutes to Imperial gallon per Years
Gallon per Minutes and Imperial gallon 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
imperial gallon per years = gallon per minutes × 437944.321266
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 imperial gallon per years equals 1.440599e-10 base units, so dividing one by the other gives the direct gallon per minutes-to-imperial gallon per years factor of 437944.321266.
Simple example
1 gal/min × 437944.3213 = 437,944.3213 imp gal/yr
1 gallon per minutes = 437,944.3213 imperial gallon per years.
Real-world example
60 gal/min × 437944.3213 = 26,276,659.28 imp gal/yr
60 gallon per minutes = 26,276,659.28 imperial gallon 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 imperial gallon per years?
Imperial gallon per Years (imp gal/yr) is a unit of flow rate.
Is the gallon per minutes to imperial gallon per years conversion exact?

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.
