About Converting Cup per Seconds to Imperial gallon per Hours
Cup 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 = cup per seconds × 187.351691542
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per seconds equals 0.0002365882365 base units, and 1 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct cup per seconds-to-imperial gallon per hours factor of 187.351691542.
Simple example
1 cup/s × 187.3516915 = 187.3516915 imp gal/h
1 cup per seconds = 187.3516915 imperial gallon per hours.
Real-world example
60 cup/s × 187.3516915 = 11,241.10149 imp gal/h
60 cup per seconds = 11,241.10149 imperial gallon per hours.

Multiply the cup per seconds value by 187.3516915. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per hours back to cup per seconds?
Use the reverse factor: 1 imperial gallon per hours equals 0.0053375552 cup per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per seconds?
Cup per Seconds (cup/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 cup per seconds to imperial gallon per hours conversion exact?
Yes. Both cup per seconds and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 187.3516915 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.
