About Converting Imperial gallon per Seconds to Quart per Days
Imperial gallon per Seconds and Quart 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
quart per days = imperial gallon per seconds × 415048.294254
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 days equals 1.095316e-8 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-quart per days factor of 415048.294254.
Simple example
1 imp gal/s × 415048.2943 = 415,048.2943 qt/d
1 imperial gallon per seconds = 415,048.2943 quart per days.
Real-world example
60 imp gal/s × 415048.2943 = 24,902,897.66 qt/d
60 imperial gallon per seconds = 24,902,897.66 quart per days.

Multiply the imperial gallon per seconds value by 415048.2943. The converter above does this instantly to whatever precision you set.
How do I convert quart per days back to imperial gallon per seconds?
Use the reverse factor: 1 quart per days equals 0.0000024094 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 days?
Quart per Days (qt/d) is a unit of flow rate.
Is the imperial gallon per seconds to quart per days conversion exact?
Yes. Both imperial gallon per seconds and quart per days are defined by fixed standards rather than physical artifacts, so the factor of 415048.2943 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.
