About Converting Imperial quart per Days to Imperial gallon per Years
Imperial quart per Days 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. Both are volumetric flow rate units.
Formula
imperial gallon per years = imperial quart per days × 91.310625
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per days equals 1.31542e-8 base units, and 1 imperial gallon per years equals 1.440599e-10 base units, so dividing one by the other gives the direct imperial quart per days-to-imperial gallon per years factor of 91.310625.
Simple example
1 imp qt/d × 91.310625 = 91.310625 imp gal/yr
1 imperial quart per days = 91.310625 imperial gallon per years.
Real-world example
60 imp qt/d × 91.310625 = 5,478.6375 imp gal/yr
60 imperial quart per days = 5,478.6375 imperial gallon per years.

What is a imperial quart per days?
Imperial quart per Days (imp qt/d) is a unit of flow rate.
What is a imperial gallon per years?
Imperial gallon per Years (imp gal/yr) is a unit of flow rate.
Is the imperial quart per days to imperial gallon per years conversion exact?
Yes. Both imperial quart per days and imperial gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 91.310625 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.
