About Converting Cup per Hours to Imperial gallon per Seconds
Cup 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 = cup per hours × 0.0000144561490387
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per hours equals 6.571895e-8 base units, and 1 imperial gallon per seconds equals 0.00454609 base units, so dividing one by the other gives the direct cup per hours-to-imperial gallon per seconds factor of 0.0000144561490387.
Simple example
1 cup/h × 0.00001445614904 = 0.0000144561 imp gal/s
1 cup per hours = 0.0000144561 imperial gallon per seconds.
Real-world example
60 cup/h × 0.00001445614904 = 0.0008673689 imp gal/s
60 cup per hours = 0.0008673689 imperial gallon per seconds.

Multiply the cup per hours value by 0.00001445614904. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to cup per hours?
Use the reverse factor: 1 imperial gallon per seconds equals 69,174.71571 cup per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per hours?
Cup per Hours (cup/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 cup per hours to imperial gallon per seconds conversion exact?
Yes. Both cup per hours and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.00001445614904 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.
