About Converting Cubic Kilometer per Weeks to Cubic foot per Seconds
Cubic Kilometer per Weeks and Cubic foot 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 foot per seconds = cubic kilometer per weeks × 58390.652648
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic kilometer per weeks equals 1653.43915344 base units, and 1 cubic foot per seconds equals 0.028316846592 base units, so dividing one by the other gives the direct cubic kilometer per weeks-to-cubic foot per seconds factor of 58390.652648.
Simple example
1 km3/wk × 58390.65265 = 58,390.65265 ft3/s
1 cubic kilometer per weeks = 58,390.65265 cubic foot per seconds.
Real-world example
60 km3/wk × 58390.65265 = 3,503,439.159 ft3/s
60 cubic kilometer per weeks = 3,503,439.159 cubic foot per seconds.

Frequently asked questions
How many cubic foot per seconds are in 1 cubic kilometer per weeks?
1 cubic kilometer per weeks equals 58,390.65265 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic kilometer per weeks to cubic foot per seconds?
Multiply the cubic kilometer per weeks value by 58390.65265. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to cubic kilometer per weeks?
Use the reverse factor: 1 cubic foot per seconds equals 0.000017126 cubic kilometer per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic kilometer per weeks?
Cubic Kilometer per Weeks (km3/wk) is a unit of flow rate.
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.
Is the cubic kilometer per weeks to cubic foot per seconds conversion exact?
Yes. Both cubic kilometer per weeks and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 58390.65265 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.
