About Converting Imperial quart per Seconds to Imperial gallon per Days
Imperial quart per Seconds and Imperial gallon per Days 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 days = imperial quart per seconds × 21600
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 imperial gallon per days equals 5.261678e-8 base units, so dividing one by the other gives the direct imperial quart per seconds-to-imperial gallon per days factor of 21600.
Simple example
1 imp qt/s × 21600 = 21,600 imp gal/d
1 imperial quart per seconds = 21,600 imperial gallon per days.
Real-world example
60 imp qt/s × 21600 = 1,296,000 imp gal/d
60 imperial quart per seconds = 1,296,000 imperial gallon per days.

Frequently asked questions
How many imperial gallon per days are in 1 imperial quart per seconds?
1 imperial quart per seconds equals 21,600 imperial gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per seconds to imperial gallon per days?
Multiply the imperial quart per seconds value by 21600. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per days back to imperial quart per seconds?
Use the reverse factor: 1 imperial gallon per days equals 0.0000462963 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 imperial gallon per days?
Imperial gallon per Days (imp gal/d) is a unit of flow rate.
Is the imperial quart per seconds to imperial gallon per days conversion exact?
Yes. Both imperial quart per seconds and imperial gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 21600 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.
