About Converting Gallon per Seconds to Imperial gallon per Seconds
Gallon per Seconds 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 = gallon per seconds × 0.832674184629
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 seconds equals 0.00454609 base units, so dividing one by the other gives the direct gallon per seconds-to-imperial gallon per seconds factor of 0.832674184629.
Simple example
1 gal/s × 0.8326741846 = 0.8326741846 imp gal/s
1 gallon per seconds = 0.8326741846 imperial gallon per seconds.
Real-world example
60 gal/s × 0.8326741846 = 49.96045108 imp gal/s
60 gallon per seconds = 49.96045108 imperial gallon per seconds.

Frequently asked questions
How many imperial gallon per seconds are in 1 gallon per seconds?
1 gallon per seconds equals 0.8326741846 imperial gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to imperial gallon per seconds?
Multiply the gallon per seconds value by 0.8326741846. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to gallon per seconds?
Use the reverse factor: 1 imperial gallon per seconds equals 1.200949926 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 seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
Is the gallon per seconds to imperial gallon per seconds conversion exact?
Yes. Both gallon per seconds and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.8326741846 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.
