About Converting Imperial gallon per Seconds to Imperial quart per Seconds
Imperial gallon per Seconds and Imperial quart 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 quart per seconds = imperial gallon per seconds × 4
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per seconds equals 0.00454609 base units, and 1 imperial quart per seconds equals 0.0011365225 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-imperial quart per seconds factor of 4.
Simple example
1 imp gal/s × 4 = 4 imp qt/s
1 imperial gallon per seconds = 4 imperial quart per seconds.
Real-world example
60 imp gal/s × 4 = 240 imp qt/s
60 imperial gallon per seconds = 240 imperial quart per seconds.

Frequently asked questions
How many imperial quart per seconds are in 1 imperial gallon per seconds?
1 imperial gallon per seconds equals 4 imperial quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per seconds to imperial quart per seconds?
Multiply the imperial gallon per seconds value by 4. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per seconds back to imperial gallon per seconds?
Use the reverse factor: 1 imperial quart per seconds equals 0.25 imperial gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
What is a imperial quart per seconds?
Imperial quart per Seconds (imp qt/s) is a unit of flow rate.
Is the imperial gallon per seconds to imperial quart per seconds conversion exact?
Yes. Both imperial gallon per seconds and imperial quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 4 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.
