About Converting Cup per Seconds to Gallon per Seconds
Cup per Seconds and Gallon 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
gallon per seconds = cup per seconds × 0.0625
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 seconds equals 0.003785411784 base units, so dividing one by the other gives the direct cup per seconds-to-gallon per seconds factor of 0.0625.
Simple example
1 cup/s × 0.0625 = 0.0625 gal/s
1 cup per seconds = 0.0625 gallon per seconds.
Real-world example
60 cup/s × 0.0625 = 3.75 gal/s
60 cup per seconds = 3.75 gallon per seconds.

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