About Converting Cubic Millimeter per Seconds to Kiloliter per Years
Cubic Millimeter 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. Both are volumetric flow rate units.
Formula
kiloliter per years = cubic millimeter per seconds × 0.031556952
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per seconds equals 1e-9 base units, and 1 kiloliter per years equals 3.168874e-8 base units, so dividing one by the other gives the direct cubic millimeter per seconds-to-kiloliter per years factor of 0.031556952.
Simple example
1 mm3/s × 0.031556952 = 0.031556952 kL/yr
1 cubic millimeter per seconds = 0.031556952 kiloliter per years.
Real-world example
60 mm3/s × 0.031556952 = 1.89341712 kL/yr
60 cubic millimeter per seconds = 1.89341712 kiloliter per years.

Frequently asked questions
How many kiloliter per years are in 1 cubic millimeter per seconds?
1 cubic millimeter per seconds equals 0.031556952 kiloliter per years, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per seconds to kiloliter per years?
Multiply the cubic millimeter per seconds value by 0.031556952. The converter above does this instantly to whatever precision you set.
How do I convert kiloliter per years back to cubic millimeter per seconds?
Use the reverse factor: 1 kiloliter per years equals 31.68873851 cubic millimeter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per seconds?
Cubic Millimeter per Seconds (mm3/s) is a unit of flow rate.
What is a kiloliter per years?
Kiloliter per Years (kL/yr) is a unit of flow rate.
Is the cubic millimeter per seconds to kiloliter per years conversion exact?
Yes. Both cubic millimeter per seconds and kiloliter per years are defined by fixed standards rather than physical artifacts, so the factor of 0.031556952 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.
