About Converting Cubic foot per Seconds to Cubic Kilometer per Minutes
Cubic foot per Seconds and Cubic Kilometer per Minutes 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 minutes = cubic foot per seconds × 1.699011e-9
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 minutes equals 16666666.6667 base units, so dividing one by the other gives the direct cubic foot per seconds-to-cubic kilometer per minutes factor of 1.699011e-9.
Simple example
1 ft3/s × 1.699011e-9 = 1.699011e-9 km3/min
1 cubic foot per seconds = 1.699011e-9 cubic kilometer per minutes.
Real-world example
60 ft3/s × 1.699011e-9 = 1.019406e-7 km3/min
60 cubic foot per seconds = 1.019406e-7 cubic kilometer per minutes.

Frequently asked questions
How many cubic kilometer per minutes are in 1 cubic foot per seconds?
1 cubic foot per seconds equals 1.699011e-9 cubic kilometer per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per seconds to cubic kilometer per minutes?
Multiply the cubic foot per seconds value by 1.699011e-9. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per minutes back to cubic foot per seconds?
Use the reverse factor: 1 cubic kilometer per minutes equals 588,577,778.7 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 minutes?
Cubic Kilometer per Minutes (km3/min) is a unit of flow rate.
Is the cubic foot per seconds to cubic kilometer per minutes conversion exact?
Yes. Both cubic foot per seconds and cubic kilometer per minutes are defined by fixed standards rather than physical artifacts, so the factor of 1.699011e-9 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.
