About Converting Cubic Meter per Years to Cubic Millimeters per Millisecond
Cubic Meter 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 = cubic meter per years × 0.0316887385068
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per years equals 3.168874e-8 base units, and 1 cubic millimeter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct cubic meter per years-to-cubic millimeter per millisecond factor of 0.0316887385068.
Simple example
1 m3/yr × 0.03168873851 = 0.0316887385 mm3/ms
1 cubic meter per years = 0.0316887385 cubic millimeters per millisecond.
Real-world example
60 m3/yr × 0.03168873851 = 1.90132431 mm3/ms
60 cubic meter per years = 1.90132431 cubic millimeters per millisecond.

Frequently asked questions
How many cubic millimeters per millisecond are in 1 cubic meter per years?
1 cubic meter per years equals 0.0316887385 cubic millimeters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per years to cubic millimeter per millisecond?
Multiply the cubic meter per years value by 0.03168873851. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per millisecond back to cubic meter per years?
Use the reverse factor: 1 cubic millimeter per millisecond equals 31.556952 cubic meter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per years?
Cubic Meter per Years (m3/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 cubic meter per years to cubic millimeter per millisecond conversion exact?
Yes. Both cubic meter per years and cubic millimeter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.03168873851 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.
