About Converting Gallon per Days to Cubic inch per Years
Gallon per Days 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 days × 84371.0175
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 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 days-to-cubic inch per years factor of 84371.0175.
Simple example
1 gal/d × 84371.0175 = 84,371.0175 in3/yr
1 gallon per days = 84,371.0175 cubic inch per years.
Real-world example
60 gal/d × 84371.0175 = 5,062,261.05 in3/yr
60 gallon per days = 5,062,261.05 cubic inch per years.

Frequently asked questions
How many cubic inch per years are in 1 gallon per days?
1 gallon per days equals 84,371.0175 cubic inch per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to cubic inch per years?
Multiply the gallon per days value by 84371.0175. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per years back to gallon per days?
Use the reverse factor: 1 cubic inch per years equals 0.0000118524 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) 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 days to cubic inch per years conversion exact?
Yes. Both gallon per days and cubic inch per years are defined by fixed standards rather than physical artifacts, so the factor of 84371.0175 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.
