About Converting Imperial gallon per Hours to Cubic inch per Seconds
Imperial gallon per Hours and Cubic inch 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
cubic inch per seconds = imperial gallon per hours × 0.0770609535532
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per hours equals 0.00000126280277778 base units, and 1 cubic inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct imperial gallon per hours-to-cubic inch per seconds factor of 0.0770609535532.
Simple example
1 imp gal/h × 0.07706095355 = 0.0770609536 in3/s
1 imperial gallon per hours = 0.0770609536 cubic inch per seconds.
Real-world example
60 imp gal/h × 0.07706095355 = 4.623657213 in3/s
60 imperial gallon per hours = 4.623657213 cubic inch per seconds.

Frequently asked questions
How many cubic inch per seconds are in 1 imperial gallon per hours?
1 imperial gallon per hours equals 0.0770609536 cubic inch per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per hours to cubic inch per seconds?
Multiply the imperial gallon per hours value by 0.07706095355. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per seconds back to imperial gallon per hours?
Use the reverse factor: 1 cubic inch per seconds equals 12.97674054 imperial gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
Is the imperial gallon per hours to cubic inch per seconds conversion exact?
Yes. Both imperial gallon per hours and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.07706095355 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.
