About Converting Quart per Years to Cubic Millimeter per Seconds
Quart per Years and Cubic Millimeter per Seconds 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 seconds = quart per years × 0.0299887310409
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per years equals 2.998873e-11 base units, and 1 cubic millimeter per seconds equals 1e-9 base units, so dividing one by the other gives the direct quart per years-to-cubic millimeter per seconds factor of 0.0299887310409.
Simple example
1 qt/yr × 0.02998873104 = 0.029988731 mm3/s
1 quart per years = 0.029988731 cubic millimeter per seconds.
Real-world example
60 qt/yr × 0.02998873104 = 1.799323862 mm3/s
60 quart per years = 1.799323862 cubic millimeter per seconds.

Frequently asked questions
How many cubic millimeter per seconds are in 1 quart per years?
1 quart per years equals 0.029988731 cubic millimeter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert quart per years to cubic millimeter per seconds?
Multiply the quart per years value by 0.02998873104. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per seconds back to quart per years?
Use the reverse factor: 1 cubic millimeter per seconds equals 33.3458591 quart per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per years?
Quart per Years (qt/yr) is a unit of flow rate.
What is a cubic millimeter per seconds?
Cubic Millimeter per Seconds (mm3/s) is a unit of flow rate.
Is the quart per years to cubic millimeter per seconds conversion exact?
Yes. Both quart per years and cubic millimeter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.02998873104 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.
