About Converting Cubic Millimeter per Years to Cubic yards per Millisecond
Cubic Millimeter per Years and Cubic yard 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 yards per millisecond = cubic millimeter per years × 4.144731e-20
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per years equals 3.168874e-17 base units, and 1 cubic yard per millisecond equals 764.554857984 base units, so dividing one by the other gives the direct cubic millimeter per years-to-cubic yard per millisecond factor of 4.144731e-20.
Simple example
1 mm3/yr × 4.144731e-20 = 4.144731e-20 yd3/ms
1 cubic millimeter per years = 4.144731e-20 cubic yards per millisecond.
Real-world example
60 mm3/yr × 4.144731e-20 = 2.486838e-18 yd3/ms
60 cubic millimeter per years = 2.486838e-18 cubic yards per millisecond.

Frequently asked questions
How many cubic yards per millisecond are in 1 cubic millimeter per years?
1 cubic millimeter per years equals 4.144731e-20 cubic yards per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per years to cubic yard per millisecond?
Multiply the cubic millimeter per years value by 4.144731e-20. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per millisecond back to cubic millimeter per years?
Use the reverse factor: 1 cubic yard per millisecond equals 2.412702e+19 cubic millimeter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per years?
Cubic Millimeter per Years (mm3/yr) is a unit of flow rate.
What is a cubic yard per millisecond?
Cubic yard per Millisecond (yd3/ms) is a unit of flow rate.
Is the cubic millimeter per years to cubic yard per millisecond conversion exact?
Yes. Both cubic millimeter per years and cubic yard per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 4.144731e-20 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.
