About Converting Imperial quart per Hours to Cubic foot per Minutes
Imperial quart per Hours and Cubic foot 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
cubic foot per minutes = imperial quart per hours × 0.000668931888483
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per hours equals 3.157007e-7 base units, and 1 cubic foot per minutes equals 0.0004719474432 base units, so dividing one by the other gives the direct imperial quart per hours-to-cubic foot per minutes factor of 0.000668931888483.
Simple example
1 imp qt/h × 0.0006689318885 = 0.0006689319 ft3/min
1 imperial quart per hours = 0.0006689319 cubic foot per minutes.
Real-world example
60 imp qt/h × 0.0006689318885 = 0.0401359133 ft3/min
60 imperial quart per hours = 0.0401359133 cubic foot per minutes.

Frequently asked questions
How many cubic foot per minutes are in 1 imperial quart per hours?
1 imperial quart per hours equals 0.0006689319 cubic foot per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per hours to cubic foot per minutes?
Multiply the imperial quart per hours value by 0.0006689318885. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per minutes back to imperial quart per hours?
Use the reverse factor: 1 cubic foot per minutes equals 1,494.92051 imperial quart per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per hours?
Imperial quart per Hours (imp qt/h) is a unit of flow rate.
What is a cubic foot per minutes?
Cubic foot per Minutes (ft3/min) measures volumetric flow rate. One cubic foot of volume passing a point every minute. It is classified as a US customary flow-rate unit.
Is the imperial quart per hours to cubic foot per minutes conversion exact?
Yes. Both imperial quart per hours and cubic foot per minutes are defined by fixed standards rather than physical artifacts, so the factor of 0.0006689318885 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.
