About Converting Liter per Years to Cubic Millimeters per Millisecond
Liter per Years and Cubic Millimeter 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 millimeters per millisecond = liter per years × 0.0000316887385068
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 millimeter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct liter per years-to-cubic millimeter per millisecond factor of 0.0000316887385068.
Simple example
1 L/yr × 0.00003168873851 = 0.0000316887 mm3/ms
1 liter per years = 0.0000316887 cubic millimeters per millisecond.
Real-world example
60 L/yr × 0.00003168873851 = 0.0019013243 mm3/ms
60 liter per years = 0.0019013243 cubic millimeters per millisecond.

Frequently asked questions
How many cubic millimeters per millisecond are in 1 liter per years?
1 liter per years equals 0.0000316887 cubic millimeters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert liter per years to cubic millimeter per millisecond?
Multiply the liter per years value by 0.00003168873851. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per millisecond back to liter per years?
Use the reverse factor: 1 cubic millimeter per millisecond equals 31,556.952 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 millimeter per millisecond?
Cubic Millimeter per Millisecond (mm3/ms) is a unit of flow rate.
Is the liter per years to cubic millimeter per millisecond conversion exact?
Yes. Both liter per years and cubic millimeter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00003168873851 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.
