About Converting Cubic foot per Seconds to Cubic Kilometer per Decades
Cubic foot per Seconds and Cubic Kilometer per Decades 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 kilometer per decades = cubic foot per seconds × 0.00893593368695
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 kilometer per decades equals 3.16887385068 base units, so dividing one by the other gives the direct cubic foot per seconds-to-cubic kilometer per decades factor of 0.00893593368695.
Simple example
1 ft3/s × 0.008935933687 = 0.0089359337 km3/decade
1 cubic foot per seconds = 0.0089359337 cubic kilometer per decades.
Real-world example
60 ft3/s × 0.008935933687 = 0.5361560212 km3/decade
60 cubic foot per seconds = 0.5361560212 cubic kilometer per decades.

Frequently asked questions
How many cubic kilometer per decades are in 1 cubic foot per seconds?
1 cubic foot per seconds equals 0.0089359337 cubic kilometer per decades, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per seconds to cubic kilometer per decades?
Multiply the cubic foot per seconds value by 0.008935933687. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per decades back to cubic foot per seconds?
Use the reverse factor: 1 cubic kilometer per decades equals 111.9077239 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 kilometer per decades?
Cubic Kilometer per Decades (km3/decade) is a unit of flow rate.
Is the cubic foot per seconds to cubic kilometer per decades conversion exact?
Yes. Both cubic foot per seconds and cubic kilometer per decades are defined by fixed standards rather than physical artifacts, so the factor of 0.008935933687 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.
