About Converting Cubic foot per Weeks to Cubic yard per Seconds
Cubic foot per Weeks and Cubic yard 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 yard per seconds = cubic foot per weeks × 6.123849e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per weeks equals 4.682018e-8 base units, and 1 cubic yard per seconds equals 0.764554857984 base units, so dividing one by the other gives the direct cubic foot per weeks-to-cubic yard per seconds factor of 6.123849e-8.
Simple example
1 ft3/wk × 6.123849e-8 = 6.123849e-8 yd3/s
1 cubic foot per weeks = 6.123849e-8 cubic yard per seconds.
Real-world example
60 ft3/wk × 6.123849e-8 = 0.0000036743 yd3/s
60 cubic foot per weeks = 0.0000036743 cubic yard per seconds.

What is a cubic foot per weeks?
Cubic foot per Weeks (ft3/wk) is a unit of flow rate.
What is a cubic yard per seconds?
Cubic yard per Seconds (yd3/s) is a unit of flow rate.
Is the cubic foot per weeks to cubic yard per seconds conversion exact?
Yes. Both cubic foot per weeks and cubic yard per seconds are defined by fixed standards rather than physical artifacts, so the factor of 6.123849e-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.
