About Converting Milliliter per Seconds to Kiloliter per Years
Milliliter 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 = milliliter per seconds × 31.556952
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per seconds equals 0.000001 base units, and 1 kiloliter per years equals 3.168874e-8 base units, so dividing one by the other gives the direct milliliter per seconds-to-kiloliter per years factor of 31.556952.
Simple example
1 mL/s × 31.556952 = 31.556952 kL/yr
1 milliliter per seconds = 31.556952 kiloliter per years.
Real-world example
60 mL/s × 31.556952 = 1,893.41712 kL/yr
60 milliliter per seconds = 1,893.41712 kiloliter per years.

Frequently asked questions
How many kiloliter per years are in 1 milliliter per seconds?
1 milliliter per seconds equals 31.556952 kiloliter per years, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per seconds to kiloliter per years?
Multiply the milliliter per seconds value by 31.556952. The converter above does this instantly to whatever precision you set.
How do I convert kiloliter per years back to milliliter per seconds?
Use the reverse factor: 1 kiloliter per years equals 0.0316887385 milliliter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per seconds?
Milliliter per Seconds (mL/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 milliliter per seconds to kiloliter per years conversion exact?
Yes. Both milliliter per seconds and kiloliter per years are defined by fixed standards rather than physical artifacts, so the factor of 31.556952 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.
