About Converting Gallon per Seconds to Imperial gallon per Days
Gallon 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 = gallon per seconds × 71943.0495519
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 imperial gallon per days equals 5.261678e-8 base units, so dividing one by the other gives the direct gallon per seconds-to-imperial gallon per days factor of 71943.0495519.
Simple example
1 gal/s × 71943.04955 = 71,943.04955 imp gal/d
1 gallon per seconds = 71,943.04955 imperial gallon per days.
Real-world example
60 gal/s × 71943.04955 = 4,316,582.973 imp gal/d
60 gallon per seconds = 4,316,582.973 imperial gallon per days.

Frequently asked questions
How many imperial gallon per days are in 1 gallon per seconds?
1 gallon per seconds equals 71,943.04955 imperial gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to imperial gallon per days?
Multiply the gallon per seconds value by 71943.04955. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per days back to gallon per seconds?
Use the reverse factor: 1 imperial gallon per days equals 0.0000138999 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/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 gallon per seconds to imperial gallon per days conversion exact?
Yes. Both gallon per seconds and imperial gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 71943.04955 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.
