About Converting Cubic inch per Seconds to Gallon per Decades
Cubic inch per Seconds and Gallon per Decades 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 decades = cubic inch per seconds × 1366101.81818
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per seconds equals 0.000016387064 base units, and 1 gallon per decades equals 1.199549e-11 base units, so dividing one by the other gives the direct cubic inch per seconds-to-gallon per decades factor of 1366101.81818.
Simple example
1 in3/s × 1366101.818 = 1,366,101.818 gal/decade
1 cubic inch per seconds = 1,366,101.818 gallon per decades.
Real-world example
60 in3/s × 1366101.818 = 81,966,109.09 gal/decade
60 cubic inch per seconds = 81,966,109.09 gallon per decades.

Frequently asked questions
How many gallon per decades are in 1 cubic inch per seconds?
1 cubic inch per seconds equals 1,366,101.818 gallon per decades, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per seconds to gallon per decades?
Multiply the cubic inch per seconds value by 1366101.818. The converter above does this instantly to whatever precision you set.
How do I convert gallon per decades back to cubic inch per seconds?
Use the reverse factor: 1 gallon per decades equals 7.320099e-7 cubic inch per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
What is a gallon per decades?
Gallon per Decades (gal/decade) is a unit of flow rate.
Is the cubic inch per seconds to gallon per decades conversion exact?
Yes. Both cubic inch per seconds and gallon per decades are defined by fixed standards rather than physical artifacts, so the factor of 1366101.818 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.
