About Converting Imperial gallon per Seconds to Quart per Seconds
Imperial gallon per Seconds and 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
quart per seconds = imperial gallon per seconds × 4.80379970202
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 quart per seconds equals 0.000946352946 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-quart per seconds factor of 4.80379970202.
Simple example
1 imp gal/s × 4.803799702 = 4.803799702 qt/s
1 imperial gallon per seconds = 4.803799702 quart per seconds.
Real-world example
60 imp gal/s × 4.803799702 = 288.2279821 qt/s
60 imperial gallon per seconds = 288.2279821 quart per seconds.

Multiply the imperial gallon per seconds value by 4.803799702. The converter above does this instantly to whatever precision you set.
How do I convert quart per seconds back to imperial gallon per seconds?
Use the reverse factor: 1 quart per seconds equals 0.2081685462 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 quart per seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
Is the imperial gallon per seconds to quart per seconds conversion exact?
Yes. Both imperial gallon per seconds and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 4.803799702 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.
