About Converting Cubic foot per Seconds to Metric cup per Weeks
Cubic foot per Seconds and Metric cup per Weeks 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
metric cup per weeks = cubic foot per seconds × 68504115.2754
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 metric cup per weeks equals 4.133598e-10 base units, so dividing one by the other gives the direct cubic foot per seconds-to-metric cup per weeks factor of 68504115.2754.
Simple example
1 ft3/s × 68504115.28 = 68,504,115.28 metric cup/wk
1 cubic foot per seconds = 68,504,115.28 metric cup per weeks.
Real-world example
60 ft3/s × 68504115.28 = 4,110,246,917 metric cup/wk
60 cubic foot per seconds = 4,110,246,917 metric cup per weeks.

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.
