About Converting Cubic inch per Seconds to Imperial gallon per Hours
Cubic inch per Seconds and Imperial gallon per Hours 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 hours = cubic inch per seconds × 12.9767405397
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 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct cubic inch per seconds-to-imperial gallon per hours factor of 12.9767405397.
Simple example
1 in3/s × 12.97674054 = 12.97674054 imp gal/h
1 cubic inch per seconds = 12.97674054 imperial gallon per hours.
Real-world example
60 in3/s × 12.97674054 = 778.6044324 imp gal/h
60 cubic inch per seconds = 778.6044324 imperial gallon per hours.

How do I convert imperial gallon per hours back to cubic inch per seconds?
Use the reverse factor: 1 imperial gallon per hours equals 0.0770609536 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 imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
Is the cubic inch per seconds to imperial gallon per hours conversion exact?
Yes. Both cubic inch per seconds and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 12.97674054 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.
