About Converting Kiloliter per Seconds to Cubic foot per Seconds
Kiloliter per Seconds 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 = kiloliter per seconds × 35.3146667215
This factor comes from each unit's defined relationship to the category's base unit: 1 kiloliter per seconds equals 1 base unit, and 1 cubic foot per seconds equals 0.028316846592 base units, so dividing one by the other gives the direct kiloliter per seconds-to-cubic foot per seconds factor of 35.3146667215.
Simple example
1 kL/s × 35.31466672 = 35.31466672 ft3/s
1 kiloliter per seconds = 35.31466672 cubic foot per seconds.
Real-world example
60 kL/s × 35.31466672 = 2,118.880003 ft3/s
60 kiloliter per seconds = 2,118.880003 cubic foot per seconds.

Frequently asked questions
How many cubic foot per seconds are in 1 kiloliter per seconds?
1 kiloliter per seconds equals 35.31466672 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert kiloliter per seconds to cubic foot per seconds?
Multiply the kiloliter per seconds value by 35.31466672. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to kiloliter per seconds?
Use the reverse factor: 1 cubic foot per seconds equals 0.0283168466 kiloliter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a kiloliter per seconds?
Kiloliter per Seconds (kL/s) 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 kiloliter per seconds to cubic foot per seconds conversion exact?
Yes. Both kiloliter per seconds and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 35.31466672 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.
