About Converting Cubic foot per Seconds to Imperial quart per Seconds
Cubic foot per Seconds and Imperial quart 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. Cubic foot per Seconds is most often used for the standard unit used by the us geological survey for reporting river and stream discharge at gauging stations.
Formula
imperial quart per seconds = cubic foot per seconds × 24.9153418362
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per seconds equals 0.028316846592 base units, and 1 imperial quart per seconds equals 0.0011365225 base units, so dividing one by the other gives the direct cubic foot per seconds-to-imperial quart per seconds factor of 24.9153418362.
Simple example
1 ft3/s × 24.91534184 = 24.91534184 imp qt/s
1 cubic foot per seconds = 24.91534184 imperial quart per seconds.
Real-world example
60 ft3/s × 24.91534184 = 1,494.92051 imp qt/s
60 cubic foot per seconds = 1,494.92051 imperial quart per seconds.

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.
What is a imperial quart per seconds?
Imperial quart per Seconds (imp qt/s) is a unit of flow rate.
Is the cubic foot per seconds to imperial quart per seconds conversion exact?

Where is the cubic foot per seconds still used today?
United States
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.
