About Converting Quarts per Millisecond to Cubic foot per Seconds
Quart per Millisecond 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 = quarts per millisecond × 33.4201388889
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per millisecond equals 0.946352946 base units, and 1 cubic foot per seconds equals 0.028316846592 base units, so dividing one by the other gives the direct quart per millisecond-to-cubic foot per seconds factor of 33.4201388889.
Simple example
1 qt/ms × 33.42013889 = 33.42013889 ft3/s
1 quart per millisecond = 33.42013889 cubic foot per seconds.
Real-world example
60 qt/ms × 33.42013889 = 2,005.208333 ft3/s
60 quarts per millisecond = 2,005.208333 cubic foot per seconds.

Frequently asked questions
How many cubic foot per seconds are in 1 quart per millisecond?
1 quart per millisecond equals 33.42013889 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert quart per millisecond to cubic foot per seconds?
Multiply the quart per millisecond value by 33.42013889. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to quart per millisecond?
Use the reverse factor: 1 cubic foot per seconds equals 0.0299220779 quarts per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) 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 millisecond to cubic foot per seconds conversion exact?
Yes. Both quart per millisecond and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 33.42013889 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.
