About Converting Cubic inch per Hours to Imperial gallon per Seconds
Cubic inch per Hours and Imperial 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
imperial gallon per seconds = cubic inch per hours × 0.00000100129170831
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per hours equals 4.551962e-9 base units, and 1 imperial gallon per seconds equals 0.00454609 base units, so dividing one by the other gives the direct cubic inch per hours-to-imperial gallon per seconds factor of 0.00000100129170831.
Simple example
1 in3/h × 0.000001001291708 = 0.0000010013 imp gal/s
1 cubic inch per hours = 0.0000010013 imperial gallon per seconds.
Real-world example
60 in3/h × 0.000001001291708 = 0.0000600775 imp gal/s
60 cubic inch per hours = 0.0000600775 imperial gallon per seconds.

Frequently asked questions
How many imperial gallon per seconds are in 1 cubic inch per hours?
1 cubic inch per hours equals 0.0000010013 imperial gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per hours to imperial gallon per seconds?
Multiply the cubic inch per hours value by 0.000001001291708. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to cubic inch per hours?
Use the reverse factor: 1 imperial gallon per seconds equals 998,709.958 cubic inch per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per hours?
Cubic inch per Hours (in3/h) is a unit of flow rate.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
Is the cubic inch per hours to imperial gallon per seconds conversion exact?
Yes. Both cubic inch per hours and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.000001001291708 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.
