About Converting Gallon per Hours to Cubic inch per Minutes
Gallon per Hours and Cubic inch per Minutes 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 minutes = gallon per hours × 3.85
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per hours equals 0.00000105150327333 base units, and 1 cubic inch per minutes equals 2.731177e-7 base units, so dividing one by the other gives the direct gallon per hours-to-cubic inch per minutes factor of 3.85.
Simple example
1 gal/h × 3.85 = 3.85 in3/min
1 gallon per hours = 3.85 cubic inch per minutes.
Real-world example
60 gal/h × 3.85 = 231 in3/min
60 gallon per hours = 231 cubic inch per minutes.

Frequently asked questions
How many cubic inch per minutes are in 1 gallon per hours?
1 gallon per hours equals 3.85 cubic inch per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per hours to cubic inch per minutes?
Multiply the gallon per hours value by 3.85. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per minutes back to gallon per hours?
Use the reverse factor: 1 cubic inch per minutes equals 0.2597402597 gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
What is a cubic inch per minutes?
Cubic inch per Minutes (in3/min) is a unit of flow rate.
Is the gallon per hours to cubic inch per minutes conversion exact?
Yes. Both gallon per hours and cubic inch per minutes are defined by fixed standards rather than physical artifacts, so the factor of 3.85 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.
