About Converting Gallon per Seconds to Imperial gallon per Hours
Gallon 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 = gallon per seconds × 2997.62706466
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct gallon per seconds-to-imperial gallon per hours factor of 2997.62706466.
Simple example
1 gal/s × 2997.627065 = 2,997.627065 imp gal/h
1 gallon per seconds = 2,997.627065 imperial gallon per hours.
Real-world example
60 gal/s × 2997.627065 = 179,857.6239 imp gal/h
60 gallon per seconds = 179,857.6239 imperial gallon per hours.

Frequently asked questions
How many imperial gallon per hours are in 1 gallon per seconds?
1 gallon per seconds equals 2,997.627065 imperial gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to imperial gallon per hours?
Multiply the gallon per seconds value by 2997.627065. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per hours back to gallon per seconds?
Use the reverse factor: 1 imperial gallon per hours equals 0.0003335972 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/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 gallon per seconds to imperial gallon per hours conversion exact?
Yes. Both gallon per seconds and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 2997.627065 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.
