About Converting Gallon per Seconds to Cup per Days
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 = gallon per seconds × 1382400
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 cup per days equals 2.73829e-9 base units, so dividing one by the other gives the direct gallon per seconds-to-cup per days factor of 1382400.
Simple example
1 gal/s × 1382400 = 1,382,400 cup/d
1 gallon per seconds = 1,382,400 cup per days.
Real-world example
60 gal/s × 1382400 = 82,944,000 cup/d
60 gallon per seconds = 82,944,000 cup per days.

Frequently asked questions
How many cup per days are in 1 gallon per seconds?
1 gallon per seconds equals 1,382,400 cup per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to cup per days?
Multiply the gallon per seconds value by 1382400. The converter above does this instantly to whatever precision you set.
How do I convert cup per days back to gallon per seconds?
Use the reverse factor: 1 cup per days equals 7.233796e-7 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 cup per days?
Cup per Days (cup/d) is a unit of flow rate.
Is the gallon per seconds to cup per days conversion exact?
Yes. Both gallon per seconds and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 1382400 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.
