About Converting Milliliter per Years to Quart per Days
Milliliter per Years and Quart per Days 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
quart per days = milliliter per years × 0.00000289311405281
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per years equals 3.168874e-14 base units, and 1 quart per days equals 1.095316e-8 base units, so dividing one by the other gives the direct milliliter per years-to-quart per days factor of 0.00000289311405281.
Simple example
1 mL/yr × 0.000002893114053 = 0.0000028931 qt/d
1 milliliter per years = 0.0000028931 quart per days.
Real-world example
60 mL/yr × 0.000002893114053 = 0.0001735868 qt/d
60 milliliter per years = 0.0001735868 quart per days.

Frequently asked questions
How many quart per days are in 1 milliliter per years?
1 milliliter per years equals 0.0000028931 quart per days, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per years to quart per days?
Multiply the milliliter per years value by 0.000002893114053. The converter above does this instantly to whatever precision you set.
How do I convert quart per days back to milliliter per years?
Use the reverse factor: 1 quart per days equals 345,648.3159 milliliter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per years?
Milliliter per Years (mL/yr) is a unit of flow rate.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
Is the milliliter per years to quart per days conversion exact?
Yes. Both milliliter per years and quart per days are defined by fixed standards rather than physical artifacts, so the factor of 0.000002893114053 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.
