About Converting Cubic foot per Seconds to Cubic yard per Weeks
Cubic foot per Seconds and Cubic yard 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
cubic yard per weeks = cubic foot per seconds × 22400
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 cubic yard per weeks equals 0.00000126414493714 base units, so dividing one by the other gives the direct cubic foot per seconds-to-cubic yard per weeks factor of 22400.
Simple example
1 ft3/s × 22400 = 22,400 yd3/wk
1 cubic foot per seconds = 22,400 cubic yard per weeks.
Real-world example
60 ft3/s × 22400 = 1,344,000 yd3/wk
60 cubic foot per seconds = 1,344,000 cubic yard per weeks.

Frequently asked questions
How many cubic yard per weeks are in 1 cubic foot per seconds?
1 cubic foot per seconds equals 22,400 cubic yard per weeks, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per seconds to cubic yard per weeks?
Multiply the cubic foot per seconds value by 22400. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per weeks back to cubic foot per seconds?
Use the reverse factor: 1 cubic yard per weeks equals 0.0000446429 cubic foot per seconds. You can also use the swap control in the converter above to flip the direction instantly.
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 cubic yard per weeks?
Cubic yard per Weeks (yd3/wk) is a unit of flow rate.
Is the cubic foot per seconds to cubic yard per weeks conversion exact?
Yes. Both cubic foot per seconds and cubic yard per weeks are defined by fixed standards rather than physical artifacts, so the factor of 22400 used above is exact to as many digits as you choose to display.
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.
