About Converting Imperial quart per Weeks to Cubic foot per Seconds
Imperial quart per Weeks 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 = imperial quart per weeks × 6.636229e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per weeks equals 1.879171e-9 base units, and 1 cubic foot per seconds equals 0.028316846592 base units, so dividing one by the other gives the direct imperial quart per weeks-to-cubic foot per seconds factor of 6.636229e-8.
Simple example
1 imp qt/wk × 6.636229e-8 = 6.636229e-8 ft3/s
1 imperial quart per weeks = 6.636229e-8 cubic foot per seconds.
Real-world example
60 imp qt/wk × 6.636229e-8 = 0.0000039817 ft3/s
60 imperial quart per weeks = 0.0000039817 cubic foot per seconds.

Frequently asked questions
How many cubic foot per seconds are in 1 imperial quart per weeks?
1 imperial quart per weeks equals 6.636229e-8 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per weeks to cubic foot per seconds?
Multiply the imperial quart per weeks value by 6.636229e-8. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to imperial quart per weeks?
Use the reverse factor: 1 cubic foot per seconds equals 15,068,798.74 imperial quart per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per weeks?
Imperial quart per Weeks (imp qt/wk) 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 imperial quart per weeks to cubic foot per seconds conversion exact?
Yes. Both imperial quart per weeks and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 6.636229e-8 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.
