About Converting Cubic inch per Minutes to Gallon per Seconds
Cubic inch per Minutes and Gallon per Seconds 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 seconds = cubic inch per minutes × 0.0000721500721501
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per minutes equals 2.731177e-7 base units, and 1 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct cubic inch per minutes-to-gallon per seconds factor of 0.0000721500721501.
Simple example
1 in3/min × 0.00007215007215 = 0.0000721501 gal/s
1 cubic inch per minutes = 0.0000721501 gallon per seconds.
Real-world example
60 in3/min × 0.00007215007215 = 0.0043290043 gal/s
60 cubic inch per minutes = 0.0043290043 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 cubic inch per minutes?
1 cubic inch per minutes equals 0.0000721501 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per minutes to gallon per seconds?
Multiply the cubic inch per minutes value by 0.00007215007215. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to cubic inch per minutes?
Use the reverse factor: 1 gallon per seconds equals 13,860 cubic inch per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per minutes?
Cubic inch per Minutes (in3/min) is a unit of flow rate.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the cubic inch per minutes to gallon per seconds conversion exact?
Yes. Both cubic inch per minutes and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.00007215007215 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.
