About Converting Imperial quart per Seconds to Gallon per Seconds
Imperial quart per Seconds and 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
gallon per seconds = imperial quart per seconds × 0.300237481376
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per seconds equals 0.0011365225 base units, and 1 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct imperial quart per seconds-to-gallon per seconds factor of 0.300237481376.
Simple example
1 imp qt/s × 0.3002374814 = 0.3002374814 gal/s
1 imperial quart per seconds = 0.3002374814 gallon per seconds.
Real-world example
60 imp qt/s × 0.3002374814 = 18.01424888 gal/s
60 imperial quart per seconds = 18.01424888 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 imperial quart per seconds?
1 imperial quart per seconds equals 0.3002374814 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per seconds to gallon per seconds?
Multiply the imperial quart per seconds value by 0.3002374814. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to imperial quart per seconds?
Use the reverse factor: 1 gallon per seconds equals 3.330696739 imperial quart per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per seconds?
Imperial quart per Seconds (imp qt/s) is a unit of flow rate.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the imperial quart per seconds to gallon per seconds conversion exact?
Yes. Both imperial quart per seconds and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.3002374814 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.
