About Converting Gallon per Seconds to Cup per Seconds
Gallon per Seconds and Cup per Seconds 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 seconds = gallon per seconds × 16
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 seconds equals 0.0002365882365 base units, so dividing one by the other gives the direct gallon per seconds-to-cup per seconds factor of 16.
Simple example
1 gal/s × 16 = 16 cup/s
1 gallon per seconds = 16 cup per seconds.
Real-world example
60 gal/s × 16 = 960 cup/s
60 gallon per seconds = 960 cup per seconds.

Frequently asked questions
How many cup per seconds are in 1 gallon per seconds?
1 gallon per seconds equals 16 cup per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to cup per seconds?
Multiply the gallon per seconds value by 16. The converter above does this instantly to whatever precision you set.
How do I convert cup per seconds back to gallon per seconds?
Use the reverse factor: 1 cup per seconds equals 0.0625 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 seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
Is the gallon per seconds to cup per seconds conversion exact?
Yes. Both gallon per seconds and cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 16 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.
