About Converting Gallon per Years to Cubic inch per Years
Gallon per Years and Cubic inch 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 inch per years = gallon per years × 231
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 cubic inch per years equals 5.192854e-13 base units, so dividing one by the other gives the direct gallon per years-to-cubic inch per years factor of 231.
Simple example
1 gal/yr × 231 = 231 in3/yr
1 gallon per years = 231 cubic inch per years.
Real-world example
60 gal/yr × 231 = 13,860 in3/yr
60 gallon per years = 13,860 cubic inch per years.

Frequently asked questions
How many cubic inch per years are in 1 gallon per years?
1 gallon per years equals 231 cubic inch per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per years to cubic inch per years?
Multiply the gallon per years value by 231. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per years back to gallon per years?
Use the reverse factor: 1 cubic inch per years equals 0.0043290043 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 cubic inch per years?
Cubic inch per Years (in3/yr) is a unit of flow rate.
Is the gallon per years to cubic inch per years conversion exact?
Yes. Both gallon per years and cubic inch per years are defined by fixed standards rather than physical artifacts, so the factor of 231 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.
