About Converting Kiloliter per Hours to Cubic Meter per Seconds
Kiloliter per Hours and Cubic Meter 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 meter per seconds = kiloliter per hours × 0.000277777777778
This factor comes from each unit's defined relationship to the category's base unit: 1 kiloliter per hours equals 0.000277777777778 base units, and 1 cubic meter per seconds equals 1 base unit, so dividing one by the other gives the direct kiloliter per hours-to-cubic meter per seconds factor of 0.000277777777778.
Simple example
1 kL/h × 0.0002777777778 = 0.0002777778 m3/s
1 kiloliter per hours = 0.0002777778 cubic meter per seconds.
Real-world example
60 kL/h × 0.0002777777778 = 0.0166666667 m3/s
60 kiloliter per hours = 0.0166666667 cubic meter per seconds.

Frequently asked questions
How many cubic meter per seconds are in 1 kiloliter per hours?
1 kiloliter per hours equals 0.0002777778 cubic meter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert kiloliter per hours to cubic meter per seconds?
Multiply the kiloliter per hours value by 0.0002777777778. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per seconds back to kiloliter per hours?
Use the reverse factor: 1 cubic meter per seconds equals 3,600 kiloliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a kiloliter per hours?
Kiloliter per Hours (kL/h) is a unit of flow rate.
What is a cubic meter per seconds?
Cubic Meter per Seconds (m3/s) measures volumetric flow rate. The SI coherent unit for volumetric flow rate — one cubic meter of volume passing a point every second. It is classified as a SI coherent derived unit.
Is the kiloliter per hours to cubic meter per seconds conversion exact?
Yes. Both kiloliter per hours and cubic meter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0002777777778 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.
