About Converting Gallon per Seconds to Cubic yard per Years
Gallon per Seconds and Cubic yard 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
cubic yard per years = gallon per seconds × 156242.625
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 cubic yard per years equals 2.422778e-8 base units, so dividing one by the other gives the direct gallon per seconds-to-cubic yard per years factor of 156242.625.
Simple example
1 gal/s × 156242.625 = 156,242.625 yd3/yr
1 gallon per seconds = 156,242.625 cubic yard per years.
Real-world example
60 gal/s × 156242.625 = 9,374,557.5 yd3/yr
60 gallon per seconds = 9,374,557.5 cubic yard per years.

Frequently asked questions
How many cubic yard per years are in 1 gallon per seconds?
1 gallon per seconds equals 156,242.625 cubic yard per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to cubic yard per years?
Multiply the gallon per seconds value by 156242.625. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per years back to gallon per seconds?
Use the reverse factor: 1 cubic yard per years equals 0.0000064003 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 cubic yard per years?
Cubic yard per Years (yd3/yr) is a unit of flow rate.
Is the gallon per seconds to cubic yard per years conversion exact?
Yes. Both gallon per seconds and cubic yard per years are defined by fixed standards rather than physical artifacts, so the factor of 156242.625 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.
