About Converting Gallon per Years to Imperial quart per Days
Gallon per Years and Imperial quart per Days 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 quart per days = gallon per years × 0.00911913793854
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per years equals 1.199549e-10 base units, and 1 imperial quart per days equals 1.31542e-8 base units, so dividing one by the other gives the direct gallon per years-to-imperial quart per days factor of 0.00911913793854.
Simple example
1 gal/yr × 0.009119137939 = 0.0091191379 imp qt/d
1 gallon per years = 0.0091191379 imperial quart per days.
Real-world example
60 gal/yr × 0.009119137939 = 0.5471482763 imp qt/d
60 gallon per years = 0.5471482763 imperial quart per days.

What is a gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
What is a imperial quart per days?
Imperial quart per Days (imp qt/d) is a unit of flow rate.
Is the gallon per years to imperial quart per days conversion exact?
Yes. Both gallon per years and imperial quart per days are defined by fixed standards rather than physical artifacts, so the factor of 0.009119137939 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.
