About Converting Kiloliter per Years to Cubic Millimeter per Seconds
Kiloliter per Years and Cubic Millimeter 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 millimeter per seconds = kiloliter per years × 31.6887385068
This factor comes from each unit's defined relationship to the category's base unit: 1 kiloliter per years equals 3.168874e-8 base units, and 1 cubic millimeter per seconds equals 1e-9 base units, so dividing one by the other gives the direct kiloliter per years-to-cubic millimeter per seconds factor of 31.6887385068.
Simple example
1 kL/yr × 31.68873851 = 31.68873851 mm3/s
1 kiloliter per years = 31.68873851 cubic millimeter per seconds.
Real-world example
60 kL/yr × 31.68873851 = 1,901.32431 mm3/s
60 kiloliter per years = 1,901.32431 cubic millimeter per seconds.

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