About Converting Gallon per Years to Quart per Seconds
Gallon per Years and Quart per Seconds 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 seconds = gallon per years × 1.26755e-7
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 seconds equals 0.000946352946 base units, so dividing one by the other gives the direct gallon per years-to-quart per seconds factor of 1.26755e-7.
Simple example
1 gal/yr × 1.26755e-7 = 1.26755e-7 qt/s
1 gallon per years = 1.26755e-7 quart per seconds.
Real-world example
60 gal/yr × 1.26755e-7 = 0.0000076053 qt/s
60 gallon per years = 0.0000076053 quart per seconds.

Frequently asked questions
How many quart per seconds are in 1 gallon per years?
1 gallon per years equals 1.26755e-7 quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per years to quart per seconds?
Multiply the gallon per years value by 1.26755e-7. The converter above does this instantly to whatever precision you set.
How do I convert quart per seconds back to gallon per years?
Use the reverse factor: 1 quart per seconds equals 7,889,238 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 seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
Is the gallon per years to quart per seconds conversion exact?
Yes. Both gallon per years and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1.26755e-7 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.
