About Converting Gallon per Seconds to Quart per Minutes
Gallon per Seconds and Quart per Minutes 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
quart per minutes = gallon per seconds × 240
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 quart per minutes equals 0.0000157725491 base units, so dividing one by the other gives the direct gallon per seconds-to-quart per minutes factor of 240.
Simple example
1 gal/s × 240 = 240 qt/min
1 gallon per seconds = 240 quart per minutes.
Real-world example
60 gal/s × 240 = 14,400 qt/min
60 gallon per seconds = 14,400 quart per minutes.

Frequently asked questions
How many quart per minutes are in 1 gallon per seconds?
1 gallon per seconds equals 240 quart per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to quart per minutes?
Multiply the gallon per seconds value by 240. The converter above does this instantly to whatever precision you set.
How do I convert quart per minutes back to gallon per seconds?
Use the reverse factor: 1 quart per minutes equals 0.0041666667 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 quart per minutes?
Quart per Minutes (qt/min) is a unit of flow rate.
Is the gallon per seconds to quart per minutes conversion exact?
Yes. Both gallon per seconds and quart per minutes are defined by fixed standards rather than physical artifacts, so the factor of 240 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.
