About Converting Milliliter per Days to Quart per Years
Milliliter per Days and Quart 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
quart per years = milliliter per days × 0.385947443334
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per days equals 1.157407e-11 base units, and 1 quart per years equals 2.998873e-11 base units, so dividing one by the other gives the direct milliliter per days-to-quart per years factor of 0.385947443334.
Simple example
1 mL/d × 0.3859474433 = 0.3859474433 qt/yr
1 milliliter per days = 0.3859474433 quart per years.
Real-world example
60 mL/d × 0.3859474433 = 23.1568466 qt/yr
60 milliliter per days = 23.1568466 quart per years.

Frequently asked questions
How many quart per years are in 1 milliliter per days?
1 milliliter per days equals 0.3859474433 quart per years, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per days to quart per years?
Multiply the milliliter per days value by 0.3859474433. The converter above does this instantly to whatever precision you set.
How do I convert quart per years back to milliliter per days?
Use the reverse factor: 1 quart per years equals 2.591026362 milliliter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per days?
Milliliter per Days (mL/d) is a unit of flow rate.
What is a quart per years?
Quart per Years (qt/yr) is a unit of flow rate.
Is the milliliter per days to quart per years conversion exact?
Yes. Both milliliter per days and quart per years are defined by fixed standards rather than physical artifacts, so the factor of 0.3859474433 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.
