About Converting Cup per Seconds to Gallon per Days
Cup per Seconds and 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
gallon per days = cup per seconds × 5400
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per seconds equals 0.0002365882365 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct cup per seconds-to-gallon per days factor of 5400.
Simple example
1 cup/s × 5400 = 5,400 gal/d
1 cup per seconds = 5,400 gallon per days.
Real-world example
60 cup/s × 5400 = 324,000 gal/d
60 cup per seconds = 324,000 gallon per days.

Frequently asked questions
How many gallon per days are in 1 cup per seconds?
1 cup per seconds equals 5,400 gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert cup per seconds to gallon per days?
Multiply the cup per seconds value by 5400. The converter above does this instantly to whatever precision you set.
How do I convert gallon per days back to cup per seconds?
Use the reverse factor: 1 gallon per days equals 0.0001851852 cup per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
Is the cup per seconds to gallon per days conversion exact?
Yes. Both cup per seconds and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 5400 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.
