About Converting Imperial gallon per Seconds to Cup per Days
Imperial gallon per Seconds and Cup 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
cup per days = imperial gallon per seconds × 1660193.17702
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 cup per days equals 2.73829e-9 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-cup per days factor of 1660193.17702.
Simple example
1 imp gal/s × 1660193.177 = 1,660,193.177 cup/d
1 imperial gallon per seconds = 1,660,193.177 cup per days.
Real-world example
60 imp gal/s × 1660193.177 = 99,611,590.62 cup/d
60 imperial gallon per seconds = 99,611,590.62 cup per days.

Frequently asked questions
How many cup per days are in 1 imperial gallon per seconds?
1 imperial gallon per seconds equals 1,660,193.177 cup per days, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per seconds to cup per days?
Multiply the imperial gallon per seconds value by 1660193.177. The converter above does this instantly to whatever precision you set.
How do I convert cup per days back to imperial gallon per seconds?
Use the reverse factor: 1 cup per days equals 6.023395e-7 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 cup per days?
Cup per Days (cup/d) is a unit of flow rate.
Is the imperial gallon per seconds to cup per days conversion exact?
Yes. Both imperial gallon per seconds and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 1660193.177 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.
