About Converting Quart per Minutes to Cubic foot per Seconds
Quart per Minutes and Cubic foot 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
cubic foot per seconds = quart per minutes × 0.000557002314815
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per minutes equals 0.0000157725491 base units, and 1 cubic foot per seconds equals 0.028316846592 base units, so dividing one by the other gives the direct quart per minutes-to-cubic foot per seconds factor of 0.000557002314815.
Simple example
1 qt/min × 0.0005570023148 = 0.0005570023 ft3/s
1 quart per minutes = 0.0005570023 cubic foot per seconds.
Real-world example
60 qt/min × 0.0005570023148 = 0.0334201389 ft3/s
60 quart per minutes = 0.0334201389 cubic foot per seconds.

Frequently asked questions
How many cubic foot per seconds are in 1 quart per minutes?
1 quart per minutes equals 0.0005570023 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert quart per minutes to cubic foot per seconds?
Multiply the quart per minutes value by 0.0005570023148. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to quart per minutes?
Use the reverse factor: 1 cubic foot per seconds equals 1,795.324675 quart per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per minutes?
Quart per Minutes (qt/min) is a unit of flow rate.
What is a cubic foot per seconds?
Cubic foot per Seconds (ft3/s) measures volumetric flow rate. One cubic foot of volume passing a point every second. It is classified as a US customary flow-rate unit.
Is the quart per minutes to cubic foot per seconds conversion exact?
Yes. Both quart per minutes and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0005570023148 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.
