About Converting Cubic Kilometer per Years to Cubic foot per Weeks
Cubic Kilometer per Years and Cubic foot 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. Both are volumetric flow rate units.
Formula
cubic foot per weeks = cubic kilometer per years × 676817914.264
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic kilometer per years equals 31.6887385068 base units, and 1 cubic foot per weeks equals 4.682018e-8 base units, so dividing one by the other gives the direct cubic kilometer per years-to-cubic foot per weeks factor of 676817914.264.
Simple example
1 km3/yr × 676817914.3 = 676,817,914.3 ft3/wk
1 cubic kilometer per years = 676,817,914.3 cubic foot per weeks.
Real-world example
60 km3/yr × 676817914.3 = 40,609,074,860 ft3/wk
60 cubic kilometer per years = 40,609,074,860 cubic foot per weeks.

Frequently asked questions
How many cubic foot per weeks are in 1 cubic kilometer per years?
1 cubic kilometer per years equals 676,817,914.3 cubic foot per weeks, using the exact defined conversion factor rather than an estimate.
How do I convert cubic kilometer per years to cubic foot per weeks?
Multiply the cubic kilometer per years value by 676817914.3. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per weeks back to cubic kilometer per years?
Use the reverse factor: 1 cubic foot per weeks equals 1.477502e-9 cubic kilometer per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic kilometer per years?
Cubic Kilometer per Years (km3/yr) is a unit of flow rate.
What is a cubic foot per weeks?
Cubic foot per Weeks (ft3/wk) is a unit of flow rate.
Is the cubic kilometer per years to cubic foot per weeks conversion exact?
Yes. Both cubic kilometer per years and cubic foot per weeks are defined by fixed standards rather than physical artifacts, so the factor of 676817914.3 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.
