About Converting Gallon per Years to Quart per Days
Gallon per Years and 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
quart per days = gallon per years × 0.010951628028
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 quart per days equals 1.095316e-8 base units, so dividing one by the other gives the direct gallon per years-to-quart per days factor of 0.010951628028.
Simple example
1 gal/yr × 0.01095162803 = 0.010951628 qt/d
1 gallon per years = 0.010951628 quart per days.
Real-world example
60 gal/yr × 0.01095162803 = 0.6570976817 qt/d
60 gallon per years = 0.6570976817 quart per days.

How do I convert quart per days back to gallon per years?
Use the reverse factor: 1 quart per days equals 91.310625 gallon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
Is the gallon per years to quart per days conversion exact?
Yes. Both gallon per years and quart per days are defined by fixed standards rather than physical artifacts, so the factor of 0.01095162803 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.
