About Converting Liter per Years to Cubic Meters per Millisecond
Liter per Years and Cubic Meter per Millisecond 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 meters per millisecond = liter per years × 3.168874e-14
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per years equals 3.168874e-11 base units, and 1 cubic meter per millisecond equals 1000 base units, so dividing one by the other gives the direct liter per years-to-cubic meter per millisecond factor of 3.168874e-14.
Simple example
1 L/yr × 3.168874e-14 = 3.168874e-14 m3/ms
1 liter per years = 3.168874e-14 cubic meters per millisecond.
Real-world example
60 L/yr × 3.168874e-14 = 1.901324e-12 m3/ms
60 liter per years = 1.901324e-12 cubic meters per millisecond.

Frequently asked questions
How many cubic meters per millisecond are in 1 liter per years?
1 liter per years equals 3.168874e-14 cubic meters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert liter per years to cubic meter per millisecond?
Multiply the liter per years value by 3.168874e-14. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per millisecond back to liter per years?
Use the reverse factor: 1 cubic meter per millisecond equals 3.155695e+13 liter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per years?
Liter per Years (L/yr) is a unit of flow rate.
What is a cubic meter per millisecond?
Cubic Meter per Millisecond (m3/ms) is a unit of flow rate.
Is the liter per years to cubic meter per millisecond conversion exact?
Yes. Both liter per years and cubic meter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 3.168874e-14 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.
