About Converting Liters per Millisecond to Cubic Kilometer per Years
Liter per Millisecond and Cubic Kilometer 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
cubic kilometer per years = liters per millisecond × 0.031556952
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per millisecond equals 1 base unit, and 1 cubic kilometer per years equals 31.6887385068 base units, so dividing one by the other gives the direct liter per millisecond-to-cubic kilometer per years factor of 0.031556952.
Simple example
1 L/ms × 0.031556952 = 0.031556952 km3/yr
1 liter per millisecond = 0.031556952 cubic kilometer per years.
Real-world example
60 L/ms × 0.031556952 = 1.89341712 km3/yr
60 liters per millisecond = 1.89341712 cubic kilometer per years.

Frequently asked questions
How many cubic kilometer per years are in 1 liter per millisecond?
1 liter per millisecond equals 0.031556952 cubic kilometer per years, using the exact defined conversion factor rather than an estimate.
How do I convert liter per millisecond to cubic kilometer per years?
Multiply the liter per millisecond value by 0.031556952. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per years back to liter per millisecond?
Use the reverse factor: 1 cubic kilometer per years equals 31.68873851 liters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
What is a cubic kilometer per years?
Cubic Kilometer per Years (km3/yr) is a unit of flow rate.
Is the liter per millisecond to cubic kilometer per years conversion exact?
Yes. Both liter per millisecond and cubic kilometer 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.
