About Converting Cubic foot per Seconds to Kiloliter per Years
Cubic foot per Seconds and Kiloliter per Years 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
kiloliter per years = cubic foot per seconds × 893593.368695
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 kiloliter per years equals 3.168874e-8 base units, so dividing one by the other gives the direct cubic foot per seconds-to-kiloliter per years factor of 893593.368695.
Simple example
1 ft3/s × 893593.3687 = 893,593.3687 kL/yr
1 cubic foot per seconds = 893,593.3687 kiloliter per years.
Real-world example
60 ft3/s × 893593.3687 = 53,615,602.12 kL/yr
60 cubic foot per seconds = 53,615,602.12 kiloliter per years.

Frequently asked questions
How many kiloliter per years are in 1 cubic foot per seconds?
1 cubic foot per seconds equals 893,593.3687 kiloliter per years, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per seconds to kiloliter per years?
Multiply the cubic foot per seconds value by 893593.3687. The converter above does this instantly to whatever precision you set.
How do I convert kiloliter per years back to cubic foot per seconds?
Use the reverse factor: 1 kiloliter per years equals 0.0000011191 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 kiloliter per years?
Kiloliter per Years (kL/yr) is a unit of flow rate.
Is the cubic foot per seconds to kiloliter per years conversion exact?
Yes. Both cubic foot per seconds and kiloliter per years are defined by fixed standards rather than physical artifacts, so the factor of 893593.3687 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.
