About Converting Liter per Days to Cubic Millimeter per Years
Liter per Days and Cubic Millimeter 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 millimeter per years = liter per days × 365242500
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per days equals 1.157407e-8 base units, and 1 cubic millimeter per years equals 3.168874e-17 base units, so dividing one by the other gives the direct liter per days-to-cubic millimeter per years factor of 365242500.
Simple example
1 L/d × 365242500 = 365,242,500 mm3/yr
1 liter per days = 365,242,500 cubic millimeter per years.
Real-world example
60 L/d × 365242500 = 21,914,550,000 mm3/yr
60 liter per days = 21,914,550,000 cubic millimeter per years.

Frequently asked questions
How many cubic millimeter per years are in 1 liter per days?
1 liter per days equals 365,242,500 cubic millimeter per years, using the exact defined conversion factor rather than an estimate.
How do I convert liter per days to cubic millimeter per years?
Multiply the liter per days value by 365242500. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per years back to liter per days?
Use the reverse factor: 1 cubic millimeter per years equals 2.737907e-9 liter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per days?
Liter per Days (L/d) is a unit of flow rate.
What is a cubic millimeter per years?
Cubic Millimeter per Years (mm3/yr) is a unit of flow rate.
Is the liter per days to cubic millimeter per years conversion exact?
Yes. Both liter per days and cubic millimeter per years are defined by fixed standards rather than physical artifacts, so the factor of 365242500 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.
