About Converting Imperial quart per Seconds to Cubic feet per Millisecond
Imperial quart per Seconds and Cubic foot per Millisecond 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 feet per millisecond = imperial quart per seconds × 0.000040135913309
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per seconds equals 0.0011365225 base units, and 1 cubic foot per millisecond equals 28.316846592 base units, so dividing one by the other gives the direct imperial quart per seconds-to-cubic foot per millisecond factor of 0.000040135913309.
Simple example
1 imp qt/s × 0.00004013591331 = 0.0000401359 ft3/ms
1 imperial quart per seconds = 0.0000401359 cubic feet per millisecond.
Real-world example
60 imp qt/s × 0.00004013591331 = 0.0024081548 ft3/ms
60 imperial quart per seconds = 0.0024081548 cubic feet per millisecond.

Frequently asked questions
How many cubic feet per millisecond are in 1 imperial quart per seconds?
1 imperial quart per seconds equals 0.0000401359 cubic feet per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per seconds to cubic foot per millisecond?
Multiply the imperial quart per seconds value by 0.00004013591331. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per millisecond back to imperial quart per seconds?
Use the reverse factor: 1 cubic foot per millisecond equals 24,915.34184 imperial quart per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per seconds?
Imperial quart per Seconds (imp qt/s) is a unit of flow rate.
What is a cubic foot per millisecond?
Cubic foot per Millisecond (ft3/ms) is a unit of flow rate.
Is the imperial quart per seconds to cubic foot per millisecond conversion exact?
Yes. Both imperial quart per seconds and cubic foot per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00004013591331 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.
