About Converting Cubic foot per Weeks to Cubic inch per Seconds
Cubic foot per Weeks and Cubic inch 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 inch per seconds = cubic foot per weeks × 0.00285714285714
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 inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct cubic foot per weeks-to-cubic inch per seconds factor of 0.00285714285714.
Simple example
1 ft3/wk × 0.002857142857 = 0.0028571429 in3/s
1 cubic foot per weeks = 0.0028571429 cubic inch per seconds.
Real-world example
60 ft3/wk × 0.002857142857 = 0.1714285714 in3/s
60 cubic foot per weeks = 0.1714285714 cubic inch per seconds.

How do I convert cubic inch per seconds back to cubic foot per weeks?
Use the reverse factor: 1 cubic inch per seconds equals 350 cubic foot per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per weeks?
Cubic foot per Weeks (ft3/wk) is a unit of flow rate.
What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
Is the cubic foot per weeks to cubic inch per seconds conversion exact?
Yes. Both cubic foot per weeks and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.002857142857 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.
