About Converting Gallon per Seconds to Gallon per Years
Gallon per Seconds and 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
gallon per years = gallon per seconds × 31556952
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct gallon per seconds-to-gallon per years factor of 31556952.
Simple example
1 gal/s × 31556952 = 31,556,952 gal/yr
1 gallon per seconds = 31,556,952 gallon per years.
Real-world example
60 gal/s × 31556952 = 1,893,417,120 gal/yr
60 gallon per seconds = 1,893,417,120 gallon per years.

Frequently asked questions
How many gallon per years are in 1 gallon per seconds?
1 gallon per seconds equals 31,556,952 gallon per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to gallon per years?
Multiply the gallon per seconds value by 31556952. The converter above does this instantly to whatever precision you set.
How do I convert gallon per years back to gallon per seconds?
Use the reverse factor: 1 gallon per years equals 3.168874e-8 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
What is a gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
Is the gallon per seconds to gallon per years conversion exact?
Yes. Both gallon per seconds and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 31556952 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.
